PATIENCE IS THE KEY. I could've paid my debts already but I was too rushed selling my coins. A lesson learned, I guess.

Quick reminder people: PATIENCE IS KEY

"suggests" is the KEY word here.

Do you have a already existing wallet where you want to import reddits vault? The only way to setup reddits vault into a wallet via seedphrase is if you set up a fresh new wallet with the seed reddit provides. Won't work in existing ones. If you have already an existing wallet save your PRIVATE KEY (not seed) for it before you do anything else and import it again AFTER you set up reddits vault with the seed. Inconvenient i know but the only way it works to have reddits and alternative wallets in metamask for example.

So you may have heard the news that there's a fund called Grayscale Bitcoin Trust which holds Bitcoins and is tradeable. The idea is that it's a proxy for holding Bitcoin yourself and then having to manage risk of theft etc by yourself. However, Grayscale were denied the right to operate as an ETF by the SEC. Since there wasn't an easy mechanism to convert Grayscale units back into Bitcoin, this led to a substantial discount (25%?) developing on Grayscale relative to the value of their Bitcoin. With an ETF, this would be arbitraged away. Matt Levine talks about this in a newsletter today, it's worth a read. Now, a court has just overruled the SEC and stated that Grayscale can be turned into an ETF. This has caused a big rally in Bitcoin (~ 7%) because ANY BITCOIN NEWS IS GOOD NEWS FOR BITCOIN. It has also caused a rally of about 16% in Coinbase. However - KEY POINT OF THIS COMMENT - a moment's reflection will reveal: 1. Arbitraging the Grayscale unit price against Bitcoin to remove the discount, involves selling a LOT of Bitcoin. This is actually rather bad for the price of Bitcoin, to have a whale offloading a ton of them suddenly. 2. If Grayscale is a nicer alternative to holding actual Bitcoin, what do you need Coinbase for? Therefore I believe the rally in both Bitcoin and coinbase will reverse throughout the week.

`As someone who loves crypto and wants more than anything to see it succeed I am asking why has this space become over run with greed and lack of empathy?` Because it is seen as an investment as well now, so I won't bother answering something that's easily answerable. In which you're likely asking rhetorically because you already know the answer like most. `Why has number go up become the only thing that matters?` Poor people got in, they see it as their way out, they'd join the people at the top in a heart beat and betray the rest if they could. There isn't much difference at the top and bottom of the food chain. Instead of seeing Crypto as the way forward, it's the only way out in a fast time frame, and to them they don't understand anything beyond the numbers going up or down. See the typical and brazen way most of these people say things like, "don't know shit about shit", etc. They're so willing to admit how absolutely ignorant they are and they upvote each other as some sort of funny movie line (despite being overused, and always said in dozens of threads a day, you're not funny at all). `Why is it laughable to care about the tech?` It's obvious why, they don't want the world to be different. They just want to complain about the way the world is, but again, they'd happily join the people at the top. The tech is just a joke to them because this is the only way to get rich and join those people fast and escape the rat race. `Why has decentralization become a "nice to have" for a system that had the main goal of removing trust and centralization?` Money matters, they believe in compromises so that more people will jump in faster. ***"WE NEED REGULATION IT'S THE ONLY WAY FORWARD TO ADOPTION!"*** (I really want more people buying my tokens so price goes up) ***"PEOPLE LOSING THEIR CRYPTO KEY IS EXACTLY WHY THIS IS A HARD SELL TO AVERAGE FOLK AND WHY NOT EVERYONE CAN SELF CUSTODY"*** `I know these are all very hard questions and I know I will probably get downvoted to fuck for asking them but luckily that is not something that bothers me.` They're not hard questions, they're sort of self answered. And who cares if you get downvoted why mention it? People on reddit are hardly people. They come off as bots more than anything. Most threads have the same unfunny jokes, same rehashed lines, random comments nothing to do with the topic. You get more engaging discussion on 4chan about these sorts of things. `Lastly I would like to ask can we change this? Is it too late? How could we move past this OR cant we and it is all down hill from here?` You can't change the majority. It's too late. More people will jump in each cycle, but it will be less and less people who care about the system, and are looking only to benefit. They'll be redirected into the same scams in this new system that's a hybrid of traditional and new finance. It won't change how the players at the top control things. Most people get money and just end up blowing it anyways, there are biological issues at play that prevent people from being smart with time/money and it's actually really depressing when you research into it.

INAL and this is not legal advice. You prove it by saying you did NOT create a trading API key. NO MORE OF THIS "I don't believe I did" BULLSHIT. You either commit to the statement or accept the money is long gone. The 90 expiration date is amazing for you. If it's the case, but that's the back to your statement that you DID NOT CREATE A TRADING API KEY. You either know or you don't. I suggest you get to know real quick. Nobody gives a shit about what you believe or feel accept you. Tough love rant over. You got this OP! get secure in your words of choice.

Ledger recently built key extraction APIs into their firmware. Oh, whoa, holy hell, no. That's when I bailed on their hardware. API stands for Application Programming Interface. An API is basically a list of commands that, when received, output info or execute a function. For example, if you have Philips Hue smart lights, your lights have an API that allows apps to set your lights to whatever color, at whatever brightness and saturation. Pretty cool! Ledger added APIs on Ledger hardware to do KEY EXTRACTION. Granted, there are safety precautions in place, but still... Ledger hardware isn't supposed to have the ability to send the keys over the internet. That's what Ledger told us for YEARS. Then they wrote the code to do it and they put that code on our devices as part of the firmware. Hell no. That's not ok. [Here's more info, with quotes from Ledger](https://www.reddit.com/r/Bitcoin/comments/15uuhex/after_whats_felt_like_an_eternity_of_buying_2/jwu3ygy/), but this one quote pretty much says it all: > There's no backdoor and I obviously can't prove it > SOURCE: [btchip, Ledger owner & co-founder](https://np.reddit.com/r/ledgerwallet/comments/13itm7u/is_there_a_backdoor_yes_or_no/jkbvys7/) ...they can't prove their hardware doesn't have backdoors that can be exploited by them, by other companies, or by hackers?!?!? ...they can't prove their hardware is SAFE?!?!? Hell no. I'm done with Ledger.

AI's rapid growth is indeed intriguing, yet it's important not to overlook the potential of Decentralized Identity tokens like ENS, ORE, and KEY. These tokens are also paving the way for innovative advancements and could be worth exploring.

I’m not saying low fees is something you can build en entire project around, obviously. But you can’t also tell me it’s just a cute little extra. As some other fellas pointed out, low fees is KEY for mass adoption. Regular Joe won’t get involved in crypto if you tell him he’ll lose 5-10% of his money just moving around his assets. Low fees is something all crypto should point towards to. And that’s of course besides every other use every coin and project has.

This is one of the KEY aspects of using crypto: ALWAYS bookmark your crypto links and never click sponsored links (they show up before the real link).

How can I purchase $10k worth of Bitcoin and hold it for the next 5 years in anticipation of earning a 10x profit? Alternatively, I could purchase low-cap tokens like ORE, KEY, and others, which might potentially yield a 20x profit during the next bull market.

Full disclosure - this is not a pure Bitcoin response - So I don't know for sure, but this may be of some interest as with all things. Do your own diligence. But here is a long term play. 1. look into trusts. - you don't own them, you are a beneficiary, the kids(s) are beneficiaries etc. (something of a current day tax shield and a long term inheritance tax shield.. not elimination just a limitation.) 2. Find a way to "Employ" the children: * Make a side business, figure out away to put them on "Payroll" pay them \*JUST UNDER\* reportable income i think it's currently 12k a year? * Open a Custodial Roth. (This is where the need for "Income" comes from. - The need a w2/w9 for this at any age.) * Plow in as much of the "income" annually as you can for each child. ( look into the tax benefits for you as the "Business owner" * Bonus round - look into Crypto Roth's. trades / purchases/conversions/ etc. that happens within the bounds of the Roth are not taxable. Taxes are taken from the money - on the way in. so all those crypto gains from initial and subsequent investment(s) are.. :) Joyful. ​ * A good trust attorney will be \*KEY\* ​ ​ * I have worries about long term bitcoin storage, whit various devices having "issues" such that true "Cold Storage" is... well problematic for anyone whos not invested in it. Your kids probably aren't yet - but they could be in time. * A trust can be constructed to hold just about any and every asset imaginable within it. (again Do you due Diligence here for your specific case, taking into account state and federal laws where needed.) ​ The bottom line, if you throw together a Custodial Crypto Based Roth, and \*only\* funded it say from child's age 8 to 18, ( mixed in other real assets) you've probably set up that child for the retirement of dreams. If your child does this for their children, you've not propagated true Generational wealth. Best wishes on this - please do the research for your specifics to see if this is something you'd be comfortable to engage on. lastly - weather it's Bitcoin, (or other digital assets) or Cash or Gold. The main thing is to keep more than the Govt takes. (Risk and Tax Management - not complete avoidance We call that fraud, and your probably to cute to go to jail.)

I'm not a fans of memecoins, but from experience, coins with real use cases has more potentials than memecoin, especially low cap tokens, the likes of ORE, ENS & KEY are good examples

>Bad actors are the disease among the human race. ALL humans are corruptible. Incentives drive human behavior. Using the LotR analogy, when a human has access to the OneRing, they ***become*** corrupt, precisely ***because*** they have ultimate power, and ultimate power corrupts ultimately. The monopoly on violence is ultimate power. It is consentless. It cannot be shut off by the individual. "*A man is no less a slave just because he is allowed to choose a new master ever term of years*" - Lysander Spooner I'm not suggesting you can eliminate all bad actions. I'm simply saying, observing incentives and structuring incentives properly are KEY to minimizing bad actions. This means 1) acknowledging that the MoV creates perverse incentives, which can only result in bad behaviors, and 2) organizing society (if that is your intent) via peaceful voluntary means, which allows consent mechanisms (or the threat of withdrawn consent) to provide the proper incentive to shape good behaviors. But first and foremost, diagnosis of THE problem needs to be correct. Bad money is a symptom of the disease, not the disease itself. The disease is that any human CAN become corrupt, ultimate power corrupts ultimately, and THE STATE (The MoV) is ultimate power.

OCEAN is one of the token I'm looking up to do well in the next bull run, I'm also expecting to see decentralized identity tokens like ORE, ENS & KEY, with the increasing need for security in web3, I think it'll do well during the bull run.

Bitcoin is a proof-of-work system. This is KEY to understand. Bitcoin isn’t about getting rich so much as it’s about balance of power. It doesn’t matter how much one entity can accumulate, they can’t change the protocol. Their million bitcoin has the same vote as your single Satoshi. This is why centralized systems don’t like proof of work; they can’t control it. If the Microsoft’s and Micro Strategies of the world want to buy up as much bitcoin as their incentives demand, then have at it. If they want to issue stock off their bitcoin then I feel for their shareholders and anyone else who wants to trust their bitcoin with a company that’s subject to State Capture. The reason we won’t be back to business as usual in this scenario is because of bitcoin’s verifiability properties. You can’t double spend bitcoin unless you convince the IOU holders that they should trust you. Good luck convincing serious share holders who will/do know how to verify. Regarding socio-economic demographics. I’ve asked this question before, and the answer it will depend on how incentivized people are to take personal responsibility over their time.

HODL! I saw my portfolio climb up from $3k to $40k then back to just $600 because I heard HODLING IS THE KEY. Take the fucking profit out!!!!

Agreed! Accumulating altcoins during the dip can lead to great long-term gains. Researching low-cap altcoins with strong liquidity and tokenomics is key. And don't forget about assets driving web3 adoption, like decentralized identity solutions such as ORE and KEY. They can be strategic investments.

Ok-Western-5799

Absolutely, accumulating altcoins during the dip can be a smart move for long-term gains. While the market may seem slow at first, the arrival of the "fomo gang" can drive significant price increases. It's important to research low-cap altcoins with strong liquidity and tokenomics to maximize potential benefits. Additionally, investing in assets with utilities that drive web3 adoption, like decentralized identity solutions such as ORE and KEY, can be a strategic choice.

KEY TAKEAWAYS * Renewed push by traditional financial firms for bitcoin spot ETFs may boost bitcoin prices. *Analysts say the worst of the bitcoin bear market is over, prices may cross $100K over the next couple of years. *Regulatory developments and outcomes of important legal battles between the SEC and crypto platforms could have big impact on crypto markets *A recession driven by government policy could help the crypto market if it's perceived as a decentralized safe haven.

>BTC and ETH forget the rest There are numerous other tokens with diverse utilities and long-term potential, one can buy in addition to BTC and ETH In particular, tokens focused on decentralized identity (DID) like KEY, LIT, and ORE are worth considering.

DonnyDauphin

Same thing! I started buying .25 cents an hour in November 2022. I slowly increased the hourly purchase amount every week (50 cents then 75 cents etc…)Now I buy about 2.00 per hour and when it peaks if I need money I take out never more than a certain percent of my total BTC. But the KEY(for me) IS TO ALWAYS BE BUYING. It’s fun to watch the charts and I’ll liquidate some when I see it high. Still at great buy at 30k. Cheers everyone and happy Bitcoining! Best is yet to come.

Either way is possible according to ChatGPT. You just need to create an API key on CoinGecko's and then use it within this code snippet: import requests # Replace 'YOUR_API_KEY' with your actual CoinGecko API key api_key = 'YOUR_API_KEY' # Set up the request headers headers = { 'Content-Type': 'application/json', 'Authorization': f'Bearer {api_key}' } # Make GET request to fetch the portfolio data response = requests.get('https://api.coingecko.com/api/v3/account/watchlist', headers=headers) portfolio_data = response.json() # Extract relevant information from the response portfolio = portfolio_data['data']['items'] # Print portfolio data for item in portfolio: coin = item['coin'] quantity = item['quantity'] value = item['value'] print(f'Coin: {coin}, Quantity: {quantity}, Value: {value}') Make sure to replace 'YOUR_API_KEY' with your actual CoinGecko API key. The code sets up the request headers with the API key, makes a GET request to fetch the portfolio data, and extracts the relevant information from the response. It then prints the coin, quantity, and value for each item in the portfolio.

I think in the link below they acknowledge offline is the way enough times that it’s sold as that, offline but I’m no lawyer so maybe I’m wrong. See below: [Ledger Website](https://www.ledger.com/academy/how-can-you-sign-online-transactions-when-your-private-key-is-offline) Heres a Ledger article published April 2022 and updated May 9th 2023 with key takeaways of the following: KEY TAKEAWAYS: — Cryptocurrency is inherently online with blockchain transactions living on the internet, but the **internet is a bit of a dangerous place and hacking and attacking leaves online digital-funds vulnerable.** — Hardware wallets are designed to **keep private keys off the internet and away from the online connection points that hackers can get to.** First paragraphs: Your house is your sanctuary – the place where you store your most precious possessions, and where you can be absolutely sure that nobody else can come in. So imagine locking the door to your precious abode, leaving the key under the mat, and walking away…anxious yet? **An Offline Key is the Only Key** It might seem like a different world, but this scenario is not all that far away from how you handle your crypto. When you create a blockchain address, your ownership of everything stored there depends on your private keys. If someone else gets those keys, consider your stuff gone. And just like in real life, most of the threats to your private keys come from opportunists seeking easy access to your address. For crypto, these opportunists tend to reside online – so keeping your keys in an online wallet can be an open invitation to hackers looking to access your blockchain address. A key stored online is simply not safe. And that can be complicated. —————— So they acknowledge “A key stored online is simply not safe. And that can be complicated.” but now that profit is involved they solved that issue 100%…. That’s very convenient and this article was updated not even 1 week ago!

Incorrect. The hardware wallet receives a message that it signs with it's cryptographic key, which itself should never be available to the client. The key must be completely unavailable to it's host computer, otherwise it's not any better than a hot wallet on a PC. I repeat: The ENTIRE FUCKING POINT of hardware wallets is to PROTECT THE FUCKING KEY.

lol, sorry. I'm not really a python dev and chat GPT is prone to hallucinate code from time to time. I'll do one more round with chat GPT, but I'm not gonna act as a go between after this. hopefully this solves it: Apologies for the confusion. It seems that the bitcointx library does not have built-in support for XOnlyPubKey. In that case, you can use the python-bitcointx library which has support for x-only public keys and Schnorr signatures (BIP-340). First, you'll need to install python-bitcointx using pip: pip install python-bitcointx Then, modify your script as follows: python from bitcointx import set_custom_secp256k1_path set_custom_secp256k1_path('./bitcointx_secp256k1_here/libsecp256k1.2.dylib') from bitcointx.wallet import P2TRBitcoinTestnetAddress, CBitcoinTestnetExtKey from bitcointx.core import BIP340_XOnlyPubKey, CKeyBase sender_priv_key = CBitcoinTestnetExtKey('PRIVATE KEY TESTNET EXTENDED WIF') sender_pub_key = sender_priv_key.pub # Convert the public key to a BIP340 x-only public key xonly_pub_key = BIP340_XOnlyPubKey.from_pubkey(sender_pub_key) # Construct a P2TR address using the x-only public key addrs_for_script = P2TRBitcoinTestnetAddress.from_pubkey(xonly_pub_key) print(addrs_for_script)

fubungh

courtesy of ChatGPT 4 - I haven't verified this, but thought it's the type of question it'd probably be good at answering The error "not a P2TR scriptPubKey" occurs because the script you're trying to derive a P2TR address from is not a valid P2TR scriptPubKey. In your script, you're using a simple pay-to-public-key (P2PK) script: python ``` csript_from_pub = CScript([sender_pub_key, OP_CHECKSIG]) ``` To create a P2TR address, you need to construct a pay-to-taproot (P2TR) scriptPubKey using the Bitcoin Improvement Proposal (BIP) 340 specification. Here's an updated version of your script that should correctly derive a P2TR address: python ``` from bitcointx import set_custom_secp256k1_path set_custom_secp256k1_path('./bitcointx_secp256k1_here/libsecp256k1.2.dylib') from bitcointx.wallet import P2TRBitcoinTestnetAddress, CBitcoinTestnetExtKey from bitcointx.core import XOnlyPubKey from bitcointx.core.key import CKeyBase sender_priv_key = CBitcoinTestnetExtKey('PRIVATE KEY TESTNET EXTENDED WIF') sender_pub_key = sender_priv_key.pub # Convert the public key to a BIP340 x-only public key xonly_pub_key = XOnlyPubKey.from_pubkey(sender_pub_key) # Construct a P2TR address using the x-only public key addrs_for_script = P2TRBitcoinTestnetAddress.from_pubkey(xonly_pub_key) print(addrs_for_script) ``` This script first converts the public key to an x-only public key as specified in BIP340. Then, it uses the `P2TRBitcoinTestnetAddress.from_pubkey()` method to create a P2TR address from the x-only public key. Make sure to replace 'PRIVATE KEY TESTNET EXTENDED WIF' with the actual private key in extended WIF format for testnet.

KEY POINTS Tech investor Chamath Palihapitiya, who previously claimed bitcoin has replaced gold and would eventually get to $200,000, now says "crypto is dead in America." "The United States authorities have firmly pointed their guns at crypto," Palihapitiya said on the latest episode of the All-In podcast. The SEC has ramped up its enforcement of the crypto industry, bearing down on companies and projects that were allegedly selling unregistered securities.

I wasn't clear in making the KEY point - I'm trying to find the cheapest option. I trust all those I listed, but the fees with this amount obviously matter. CryptoPay had worked for me on a smaller amount yesterday but now I notice their fees are actually pretty bad.

The code you've provided is quite efficient for creating a Bitcoin native SegWit transaction with an OP\_RETURN message. However, there are a few optimizations and improvements you can make: Remove unnecessary imports: In your code, you've imported addr\_non\_seg, but it's not used anywhere. You can remove this line: addr\_non\_seg = recPrivKey.get\_public\_key().get\_address() Remove the unnecessary script code and signing flags: The 'OP\_DUP', 'OP\_HASH160', 'OP\_EQUALVERIFY', 'OP\_CHECKSIG' opcodes are necessary for P2PKH (Pay-to-Public-Key-Hash) transactions. However, you're creating a P2WPKH (Pay-to-Witness-Public-Key-Hash) transaction, which uses a different script. The script code for signing P2WPKH transactions is the public key hash (PKH) itself. You can simplify the script code as follows: script\_code = addrs\_for\_script.to\_hash160() For SegWit transactions, you don't need to use the SIGHASH\_ANYONECANPAY flag, as it's generally used for non-SegWit transactions when you want to allow others to add inputs to the transaction. You can remove it from your signing process: txsign1 = priv.sign\_segwit\_input(tx, 0, script\_code, to\_satoshis(0.00032557), SIGHASH\_ALL) Use more descriptive variable names: Using more descriptive variable names can make your code easier to understand and maintain. For example, you could replace priv with sender\_priv\_key, pub with sender\_pub\_key, recPrivKey with receiver\_priv\_key, and addr with receiver\_addr. Here's the optimized version of your code with these suggestions: from bitcoinutils.utils import to\_satoshis from bitcoinutils.setup import setup from bitcoinutils.transactions import Transaction, TxInput, TxOutput from bitcoinutils.script import Script from bitcoinutils.keys import PrivateKey as utilPrivKey from bitcoinutils.constants import SIGHASH\_ALL setup('testnet') sender\_priv\_key = utilPrivKey.from\_wif('SENDING ADDRESS PRIVATE KEY') sender\_pub\_key = sender\_priv\_key.get\_public\_key().to\_hex() addrs\_for\_script = sender\_priv\_key.get\_public\_key().get\_address() receiver\_priv\_key = utilPrivKey.from\_wif('RECEIVING ADDRESS PRIVATE KEY') receiver\_addr = receiver\_priv\_key.get\_public\_key().get\_segwit\_address() txin1 = TxInput("947145005bac29a9966403e986b8a36cb225cba504bffbb3f6c1da7dba7197be", 1) txin2 = TxInput("aea283b193f2179cb6a5c2bcea4b9ad7158960696ebfb5c15d22a0411f25dafe", 0) script\_code = addrs\_for\_script.to\_hash160() msg1 = "69eb032167c25784108b9783c9d59ce23608d00238eb9e3c03c73cdd79f74528" op\_return\_script = Script(\["OP\_RETURN", msg1\]) txoutOpR = TxOutput(0, op\_return\_script) txout = TxOutput(to\_satoshis(0.00034416), receiver\_addr.to\_script\_pub\_key()) tx = Transaction(\[txin1, txin2\], \[txoutOpR, txout\], has\_segwit=True) txsign1 = sender\_priv\_key.sign\_segwit\_input(tx, 0, script\_code, to\_satoshis(0.00032557), SIGHASH\_ALL) tx.witnesses = \[Script(\[txsign1, sender\_pub\_key\])\] txsign2 = sender\_priv\_key.sign\_segwit\_input(tx, 1, script\_code, to\_satoshis(0.00006859), SIGHASH\_ALL) tx.witnesses.append(Script(\[txsign2, sender\_pub\_key\])) signed\_tx = tx.serialize() print("raw tx below this line") print(signed\_tx) print("raw tx above this line")

Governance is KEY to Enterprises. No self respecting Enterprise or Government is going to put a mission critical use case, supporting billions of transactions onto a network with poor governance. Most L1s today have governance that is downright murky. Unkown miners or teams of developers controlling the network, each to an unknown degree, in unknown ways for unknown reasons. Its truly a minefield for any self respecting Enterprise or Government. The dangers run from outright theft and disappearance, forking, funds vanishing, the network failing, security flaws, corruption, poor performance etc, etc, etc. An Enterprise cannot have that. They simply cannot deploy on such a platform (no matter how big the potential return from the use case). So..... Along comes Hedera. A governing council of upto 39, known, term limited, international, dispersed, platform independent, organisations each of which have billions invested in their reputations, and who want a public network for the utility it provides. 39 Enterprises who meet publicly, whose minutes are formally documented and made accessible to everyone. With members with knowledge of the areas they run, who are identifiable. Each organisation with an EQUAL share of the control. The truth is, Hedera is MORE Decentralised than other networks already. This year community nodes will be added, so people outside of the Governing Council will be running nodes. I don`t know how many nodes there will be at the end of 2023, but I know it will be significantly more than 28. And that number will rise, year on year. Eventually anonymous nodes will be added and IMO the numbers will be many thousands of nodes.

I will quote /u/Ricola63 : There are two main themes to the answer. 1. There are FAR more types of use cases for a public DLT than either ETH (2.0) or its many L2`s, or any BTC variant can technically meet (OR come anywhere close to meeting). MOST of these are Enterprise usecases requiring billions of Txns to be registered on a secure Pubic Network. Hedera can meet that requirement, indeed was built for it. Since Scale will ultimately win any competitions between competing platforms it is highly likely Hedera will have scaled before other platforms can catch up. Indeed we already see this strategy paying off as Hedera is, by miles, the most used public network. Its Enterprises that bring these use cases off the bat, startups may build to those kind of massive use cases over time but Enterprises can often simply choose to move onto a Public DLT to achieve the results. 2. Governance is KEY to Enterprises. No self respecting Enterprise or Government is going to put a mission critical use case, supporting billions of transactions onto a network with poor governance.

https://en.bitcoin.it/wiki/Private_key > **Base58 Wallet Import format** > > When importing or sweeping ECDSA private keys, a shorter format known as wallet import format is often used, which offers a few advantages. The wallet import format is shorter, and includes built-in error checking codes so that typos can be automatically detected and/or corrected (which is impossible in hex format) and type bits indicating how it is intended to be used. Wallet import format is the most common way to represent private keys in Bitcoin. For private keys associated with uncompressed public keys, they are 51 characters and always start with the number 5 on mainnet (9 on testnet). Private keys associated with compressed public keys are 52 characters and start with a capital L or K on mainnet (c on testnet).

KEY POINTS The U.S. Securities and Exchange Commission (SEC) could be gearing up to take action against Paxos, a company that issued the Binance USD (BUSD) stablecoin. The SEC hasn’t begun official action. But the agency’s actions are being watched closely because if it starts an official procedure, then it could have huge implications for all stablecoins including tether and USDC. For its part, Paxos said it “categorically disagrees with the SEC staff because BUSD is not a security under the federal securities laws.”

When you initialized the ColdCard you were given a 24 word seed phrase. The seed phrase, per the algorithm laid out in BIP-39, can be used to recreate EVERY PRIVATE AND PUBLIC KEY YOUR WALLET WILL MAKE IN ITS ENTIRE LIFETIME. Trillions upon trillions of them. That's why it's so essential to protect it. If you lose your ColdCard you can import that seed into any BIP-39 compatible wallet (soft or hard), and you'll have access to the entire wallet. >Just kind of confused on why the coldcard or any cold wallet is necessarily when in reality all u need is your phrases and keys? A wallet signs transactions. If you want to hand-calculate transaction signatures using only your keys, be my guest, but after a few days of working on your first one I imagine you'll switch back to a digital wallet.

You hit the nail on the head, proper centralization is KEY to widespread adoption. People must realize that not everyone wants the pressure of holding their own coins or writing down seed phrases. Some people like to have their coins in something that reminds them of the safety banks give them and that is fine too.

Even if it's not a life changing amount, making yourself familiar with how bitcoin works can't hurt and might prove useful in the future. Basically, if you want to really *own* your bitcoin, you need a self-custody wallet. These wallets can be either a software on your phone, on your laptop or desktop or a dedicated hardware device called a *hardware wallet*. Hardware wallets are generally more secure than software wallets, software wallets on smartphones are generally more secure than on computers and there are also differences between hardware wallets. Imho the wallet software (and hardware) being *open source* is a positive, since everybody is allowed to see how exactly it works and spot weaknesses and call them out. What a (self-custody) wallet does is always the same thing: it generates a digital key, called the *private key* which allows for full access to the funds and therefore has to be kept a secret. From this private key it derives an address (which can be used to deposit funds) through the process of *hashing*. Hashing is some complicated math thing which you don't have to understand in detail (I don't either) but the important thing is that it takes any data as an input and generates a kind of digital fingerprint of that data but it *cannot* be used the other way round. So if you have the private key you can generate an address but someone that only has the address *cannot* get the private key from that, so they *cannot* spend the funds on that address. So the process works as follows: -you have a private key and a corresponding address -you give the address (NOT THE PRIVATE KEY) to someone who is supposed to give you money -they send btc to that address -you have the btc -if you want to spend it, you send it to someone else's address using your private key. Sounds a bit theoretical. In practice there are very easy to use wallets, the more secure they are the less easy they are and the least easy part is backing up your keys safely. Modern wallets also generate an almost-infinite amount of different private key address pairs so that you can use a different one for every transaction which severely enhances privacy. I suggest you watch some YouTube videos, there are great channels, two of which are BTC Sessions and aantonop. The latter one did a great talk for beginners which really helps understanding the basics: https://youtu.be/FYo5E7zT-vM

Bitcoin uses 32-byte (256 bit) private keys. There will never be more than 2^256 unique private keys. It's mathematically impossible. A [hierarchical deterministic](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki) wallet gets its 32-byte private keys from a "key tree" which it builds from a 512-bit master extended key. (An HD wallet can also build a subset of the tree from a non-master extended key, but that use case is irrelevant here.) Since extended keys are 512 bits long, there can be no more than 2^512 unique HD wallets. It's mathematically impossible. By standard, an HD wallet generates its 512-bit master extended key from [128 to 512 bits of entropy (randomness)](https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki#user-content-Master_key_generation), a.k.a. "seed value". An HD wallet that follows the [BIP-39](https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki) standard generates its 512-bit master extended key from a seed based on 128, 160, 192, 224 or 256 bits of entropy, which it encodes as a mnemonic for ease of use by human users, and an optional passphrase (additional entropy). The master extended key for a BIP-32 HD wallet is always 512 bits, and the private keys in the key tree are always 32 bytes (256 bits), but **adding a passphrase increases the entropy of the seed used to calculate the 512-bit master extended key.** What does this mean for the security of a Bitcoin wallet? First, each INDIVIDUAL private key in the wallet--regardless of how that key was generated--is equally "guessable". There are 2^256 possible Bitcoin private keys. Hence my answer to OP's "extremely small chance that someone [...] could accidentally or forcibly get into my wallet": a passphrase doesn't protect individual keys. Second, although the master extended key is always 512 bits, using a passphrase when calculating its seed increases the entropy used in its selection. Since the master extended key can reproduce EVERY private key in the key tree, using a passphrase when calculating the master extended key dramatically increases the security of the ENTIRE wallet (the key tree), but not each INDIVIDUAL KEY in the wallet.

But they ommited the KEY fact: Bitcoin was just a first Crypto experiment. True full fledged Bitcoin as it was dreamed by Satoshi is Monero. Only Monero is a CryptoCurrency since not it is only irreversible, but also completely fungible. Monero has adaptive block size, extremely low TX fees, ASIC resistant PoW algo and other properties making it the only CryptoCurrency technically ready for mass adoption. And as a cherry cake: total supply of Monero will be less than total Bitcoin supply till year 2040. You can make a new son, he gets mature 17 years old, only only then Monero supply will become higher than Bitcoin one. It grows linearly, exactly like a Gold. Yes, also Monero is true digital Gold. Since all the Gold pieces and atoms are also fully fungible.

If investing rather than trading works for you, definitely stick to it! What I've learned on my trading journey is balance is KEY. I used to be on the charts atleast 10 hours a day and it fried my brain and i would do this for months. It affected my health, relationship, etc. I mainly swing trade crypto futures and trade for no more than 3 hours a day when trading futures or options. This setup/system works perfect for me. If you were ever to get back into trading crypto/crypto futures, journal for a month and find out what. your most profitable times are, and if day trading it or swing trading is better for you based on your results/findings.

Algorand isn't doing 6000 TPS at the moment LOLLLLLLLL That's speculation. It literally says "As part of Algorand's latest major protocol upgrade, the blockchain will see a 5x performance boost to 6,000" ​ WILL IS THE KEY WORD. THAT MEANS ITS NOT HAPPENING NOW BUT GUESS WHAT, GO ON THE ALGO EXPLORER RIGHT NOW AND TELL ME HOW MANY TPS ITS DOING RIGHT NOW????? ​ ITS ONLY DOING 9 TPS AT THE MOMENT BWAHHAHAHAHAHAH ​ [https://algoexplorer.io/](https://algoexplorer.io/) ​ Love demolishing Algo bag holders with facts. This shit is too easy.

No it’s not, you’re just one of the ignorant morons too stupid to understand you’re wrong. > KEY HIGHLIGHTS > Exchanges and brokerages are different types of markets with unique functionality. > Exchanges match traders, allowing them to execute orders with each other. > Brokerages transact with their clients directly You don’t transact with Coinbase, you transact with other people. This is also one key reason trading fees goes down as your trailing volume goes up, and why stablecoin pairs don’t have fees, because they’re getting their users to add the liquidity with lower and no fees as an incentive. Please go be stupid and smug about it somewhere else.
