Out of the four or five I tried, Koinly was the best. Not perfect, but certainly more user-friendly and accurate. API integration is available with the most of the large main stream exchanges. If not, it can at least import CSV, which it will sort on its own.

Mentions:#API

Their code is closed source. API gateways were invented for unique systems to communicate with each other, and quant is the first to incorporate one with DLT. Its also patented. So chainlink basically made their own version using a DON and external databases, adding more steps to the process. Did you know CCIP partially relies on solana? If solanas down, well… Anyways, its clearly explained in quants whitepaper: https://uploads-ssl.webflow.com/6006946fee85fda61f666256/60211c93f1cc59419c779c42_Quant_Overledger_Whitepaper_Sep_2019.pdf

#Chainlink Pro-Arguments Below is an argument written by FrogsDoBeCool which won 2nd place in the Chainlink Pro-Arguments topic for a prior [Cointest](/r/CointestOfficial/wiki/cointest_policy) round. > # Chainlink - Oracles, the thing no basic crypto investor understands > > Disclaimer: I own Chainlink, and believe it's a good project. > > * Chainlink is, confusing to say the least. It does a lot. Specifically with smart contracts. I really feel like I need to explain an oracle before I dig too deep in this. (it's okay, oracles are directly related to chainlink). > > # Oracles > > * Transactions when validated need to be sequential and agreed upon with every ledger? right? yes, but [smart contracts ruin that.](https://www.youtube.com/watch?v=ZJfkNzyO7-U) (0:00-3:00, heavily referenced in oracle problem). Imagine you need to send $5 of eth to someone every minute, forever. great. cool. no. > * When we use an API in the smart contract to find the price of eth to send $5 to person A, we have to deal with the fact the price of ETH will changes, all the nodes that validate this one transaction take time to validate the transaction, therefore all the nodes validating said transaction will get a different result. Destroying the entire Ethereum network and making Vitalik cry. > * When we call transactions already validated to be checked again, the API used will be called again. So imagine sending $5 of eth to person A in 2017, which would be 0.5 eth at the time. But today 0.5 eth is worth like, $2000. So getting the history of all transactions.. can't happen. > * **How Oracles Solve this dilemma** > * Oracles in a sense connect historic data to current. They keep the data of API's, transactions, etc, so that they can bridge the differences in data and keep transactions able to be validated. For an easier explanation, they take the transaction, and bundle it, for all the nodes to get, to validate. > * **The Oracle problem** > * The reason many, many oracles have failed in the past is due to the [oracle problem](https://blog.chain.link/what-is-the-blockchain-oracle-problem/), in which we trade decentralization for well.. smart contracts to work. Because an Oracle keeps the data of all smart contract transactions to distribute to nodes to give one singular result, and the fact many oracles have used a single storage server, they're inherently centralized. It's similar to having a cryptocurrency being made on one node. > * [Centralization is not the only issue,](https://medium.com/@DelphiSystems/the-oracle-problem-856ccbdbd14f) Native blockchains cannot pull or push data onto off-chain data. This gives these networks security from hackers and vulnerabilities. Although, the world is kinda sexy with data, and apis, and oh my god. all the numbers. Smart contracts love numbers. > * How are these problems solved? Chainlink! > > # Chainlink, its use, purpose, and value > > * The actual coin, [Link](https://cryptonews.com/coins/chainlink/), is used similar to a gas payment, in which they use it to help validate transactions. It's been stated historically that Link as a coin is not needed at all, and is a useless coin.. But, nope, if that was true, then ethereum gas fees would be useless too. (while i wish gas fees were useless, they're not!) > * The more link a node has collected, [generally the more trusted it is](https://www.youtube.com/watch?v=j2fg8qGWBYE), allowing it to get more data. This one key idea would make people think Chainlink is centralized, but instead, there's been a way to increase the speed of the network and validation of transactions, since the fastest nodes are also the ones with the most link. > * Chainlink works on several blockchains > * [External adaptors](https://docs.chain.link/docs/external-adapters/) allow smart contracts to be able to be used and validated on multiple blockchains, one of the earliest examples of attempting to bridge cryptocurrencies! > * External adaptors are also what chainlink use to bridge data from API's to the blockchain network in a decentralized way. > * **The Oracle Problem** > * Chainlink solves this issue efficiently, cleanly, and thankfully easy to explain. They basically built an entire blockchain on a blockchain just for smart contracts. > * [They have decentralized nodes](https://docs.chain.link/docs/running-a-chainlink-node/). The nodes collect data from API's, then validate them via specific oracles in each node, then is sent to the blockchain. Nodes are compensated in LINK coins for this work. They also receive data from the blockchain too to then send that data usually to API's. > * Real World Use > * Data feeds is the initial problem I basically introduced in this cointest, in that we cannot know the historic value of eth on an API that's ever changing. Chainlink, because of oracles, has solved this. Don't believe me? kinda hurts, but no matter. [Here's an example.](https://data.chain.link/) Data feeds are now a basic example of what Chainlink can do, and should be known as one of the first things chainlink and oracles, in general, were built to solve. > * the entire ethereum DeFi world is built on chainlink's protocols. Yeah, by the way, Ethereum is valued at 500 billion dollars. > * Chainlink is honestly, **the bridge to the internet** \- **to the blockchain**. It is one of the most useful projects that could ever be made in crypto, and it's one of the only decentralized oracle cryptos. > * Any data that can be scraped into an API can be put onto the blockchain now because of Chainlink. Bank information, financial statements.. you could even end up building an API on r/cc to scrape data, to host a website on web 3.0 using smart contracts, and by that nature, chainlink. > * Grayscale crypto etf's have a Chainlink trust, [specifically for chainlink!](https://grayscale.com/products/grayscale-chainlink-trust/?gclid=Cj0KCQiA4b2MBhD2ARIsAIrcB-RTNwh_LNWBoCGHuRRAbQYNuwpo095BoYlYF2xFPawJecHUBNYZgwwaAoqOEALw_wcB) > * Chainlink is used everywhere in most blockchains with smart contracts, because of its decentralized, ease of use, oracles. I'm grasping at straws just simply because Chainlink seems to solve specific issues that people would not encounter in daily cryptocurrency life, but Chainlink literally is the foundation of many things cryptocurrency. That's the key takeaway from this. > > ​ > > ​ > > some cool things i found: > > when looking over reddit, i found apparently the technical community manager vibing, explaining [oracles.](https://www.reddit.com/r/CryptoTechnology/comments/81te2i/how_do_blockchainssmart_contracts_communicate/) back in 2018, when link was around $0.50.

“Chart patterns and indicators trick your brain. None of them help you predict bitcoin's price, but you've used technical analysis successfully (or know someone who has), so YOU JUST KNOW you've found an exception. You haven't. It's time to graduate and think critically. Thread 🧵 Your first mistake is thinking the chart is real. You pull up historical prices and volume and you think you're looking at history. You're not. One SEC applicant estimated that 95% of exchange-reported bitcoin transactions NEVER OCCURRED. Every chart lies. That only 5% of data is even somewhat reliably reported is only the start of the horrible reality. Consider that bitcoin's on-chain transaction volume during a typical 24hr period sums to just $8B. CoinMarketCap reports $34B in spot plus $50B in derivatives volume. $8B vs. $84B. So not only could 95% be lies, 90% of real transactions occur off-chain on exchange-controlled servers. No blockchain forensics can help you decipher truth there. Trades are occurring within the exchange alone, reported to the world in a single API. Good luck verifying that. False data from exchanges ⏤ even reputable exchanges ⏤ is rampant and pervasive. Every exchange in the world has revised its historical data. The CFTC just sued Gemini's bitcoin billionaires with enabling wash trading on their own New York-based, BitLicensed, insured exchange. Worse, crypto's largest transactions occur over-the-counter; OTC desks never report data publicly. In 2021, a single OTC desk originated $130B in loans, and traded $116B in spot volume plus $53B in derivatives notional value. All that data? Confidential. Excluded from all charts. Your next mistake is thinking that because your charting expert (friend, teacher, book author) is profitable, they must have found an exceptional method that uses charting successfully. What you're forgetting is Statistics 101: the bell curve. Let's say I give $1,000 each to 1,000 people, instructing them to use whatever charting technique they want to trade. How many traders will end the month in profit? Dozens, certainly, if not hundreds! Now, should I extend their employment to have them teach a course on their masterful technical analysis? You see, it's exceedingly difficult to apply logic when listening to someone's personal story. It is, after all, their lived experience. They studied charts diligently, applied a consistent method, and ended their trading career in profit. They just MUST have a true skill! However, what you realize as an adult is that at any given time, given that there are millions of people trading the markets using charting techniques, there will always ⏤ indeed, there MUST BE ⏤ thousands of fabulously profitable traders. This is the law of large numbers. The winners are the survivors, and they always have good motivation to explain their success. They teach courses and conduct interviews and will speak with you one-on-one to verify that they truly made a profit with charts. They really have the money. But your final mistake is the most elementary: correlation versus causation. In the world, there are survivors. Enlist a million traders into crypto markets, and hundreds of new millionaires will emerge victorious. But charting did not cause their success.

I use Bitcoin DCA as follows... My UK Bank (Bank A) doesn't allow money transfers to crypto exchanges, so I have to use an interim bank (Bank B) Every monthly paycheck i auto transfer 1000 from bank A to Bank B. Weekly Bank B auto transfers 200 to Kraken on a Wednesday at 00:00 I have a Linux virtual machine running Bitcoin DCA. Every Thursday at 13:37 Bitcoin DCA buys 200 worth of Bitcoin via the Kraken API and then sends me a Telegram message to tell me it's done. Every Friday at 16:20 Bitcoin DCA tells Kraken to send all the Bitcoin in my account to my Ledger. Then sends me a Telegram Message to tell me it's done. The Kraken API is restricted to only buy and can only send to pre-approved addresses. In this case - my Ledger. If I want to check my Ledger balance I just check the Ledger App on my phone. I never have to actually touch the Ledger. I haven't touched it for a year apart from to check it still powers up. It took a few hours to set up, but the Bitcoin DCA docs are very good and after that its 100% hands free and my Ledger is never exposed. When I develop a positive balance in Kraken due to the fact there are not always 5 transfer days in a month,I might buy some shitcoins, or a dip if there is one.

> how can that new wallet fetch all my transaction history just from a Merkle root hashes? It can not. A client can send a list of addresses to a node as a Bloom filter (few nodes support this now) or a compact block filter. The node uses Merkle branches to discover a list of possible candidates, with some false positives. The client filters out the false positives But most light wallets rely on a server which has an index of transactions by address. Sometimes this server is centralized, maintained by the wallet developer, or it is paid API access to a Web block explorer, or a volunteer-operated Electrum server If you run your own node, and you need to rebuild history from nothing, your node will rescan the entire blockchain to discover transaction history. This takes about 3 hours

öhm, from my understanding there is no price feed on a pulbic chain. How would that work? In every block a few byte of the actual price of some token? Smart contracts have to call the API to get the price of whatever and than the the data is processed. there is no data of any price in any block on the chain. And even if - how would anyone ever know in what block what bytes would mean the price of whatever token? I'm no blockchain expert, but what you say just does not makes sens to me

Mentions:#API

From what I've seen, they do provide a public API that you can freely access and you can use their aggregator interface but you would have to build your own external adapter to build anything meaningful. Simply being able to view a public feed isn't the same as using their oracle or services. You need to to transact link in order to utilize request/response job executions for more external complex and meaningful data. I guess the idea is that oracles are a entirely concept from your run of the mill price feed.

Whoa surprise - another instantly downvoted thread about ICP. Other chains really seethe about ICP's tech. * Full stacks on chains, tamper proof software * Serve web content directly from smart contracts * Integration with other blockchains with no bridges * Run front ends for all chains * Solve de-platforming risks for applications * Scale other protocols like ETH and others * Add smart contract to BTC, doge, and other non smart contract platform * On chain Governance clients for other protocols, enterprises, and governments * Build user owned and controlled social networks in which each account is smart contract and can be moved to different dAPPS by the user. * NFTs live entirely on-chain (files and assets) and can react to the outside world via https request * No need for Oracles for some API calls as the protocol can communicate directly with Web 2 and run the data through consensus <---downvote over here if you're seething

Prizes can generate excitement but definitely can introduce incentive for cheating/abuse, so bit of a double-edged sword. As far as game mode, perhaps a separate "real-time" leaderboard would function only for real time results via API?

No idea why you'd keep bulk money on metamask. Get an exchange account and start using a bot to trade automatically through API keys.

Mentions:#API

Pure manipulation, it does nothing special, and it'll be coming back down. Their entire model is API's to connect chains - ICP uses direct integration (more secure, faster, cheaper) and no bridges to connect chains. That's just one feature of ICP in addition to everything else it does. CKB is better for multi chain environments too along with DOT and and LINK with CCIP when it's out.

Use an app like cryptotaxcalculator or koinly. They connect via API and do all the calculations for you. They even generate reports that you use for tax purposes. Very easy and automated.

Mentions:#API

As someone that wasted many hours with Python and the Binance API, I can attest to all of this.

Mentions:#API

I agree, its not a one size fits all. Different levels of activity will warrant different levels of due diligence. Importing is definitely nice. The only hang up is when you start moving assets from other places and the exchange has no way to track your cost basis. It could end up biting you later. I use Koinly and I can either import or use API to connect for all of the platforms I use and its pretty simple, but I also keep a spreadsheet to check against it because I "trust but verify"

Mentions:#API

If I remember correctly, the code was opensourced when the exchange shut down. Unfortunately, the hardcoded API keys for 3rd party services were not scrubbed, leading to further financial loss.

Mentions:#API

I used the API directly from the CEX and imported via TurboTax (I think they use Cointracker) It’s still kinda inaccurate and requires manual work. But 80%+ of transactions were imported successfully My main concern was making sure all my big profit sales were accounted for. I want NO problems with the IRS. NONE.

Mentions:#API#CEX

Pay for something that integrates with the API of whatever exchange you're using. Anything else is not worth the headache.

Mentions:#API

I used a site called [bitcoin.tax](https://bitcoin.tax). The actual capital gains tax calculation is (I assume) based on American tax rules, so ignore that bit if you're not in the US. It still calculates your total gains accurately, assuming you give it accurate records. It uses API keys from most crypto exchanges to automatically look up your transactions. As for defi, you'll probably have to do that manually. I never got into that stuff, so I can't really advise there.

Mentions:#API

Anyone know of a reliable API that I can pull TA data from - i.e. pre-calculated ma, ewma, rsi, macd etc?

Mentions:#API

I looked it up and it seems pretty decent. I used 2 others in the past and they got it done but had issues. Do the API's auto sync? Also is there a promo code anywhere?

Mentions:#API

I don't trade much I mainly buy on coinbase and hodl so its not that many transactions to track, which is via a read-only API key generated by coinbase that only grants permission to see the address' transactions. Koinly or cointracker import the (again read-only)API key and generate a list of you transactions from that exchange, I expect most cexs like binance can make api keys for software like this too. More transactions create a higher cost from cointracker I cant speak for koinly...

Mentions:#API

The paid version of cointracker has API access to some exchanges, so you can upload a read-only API key linked to your account and it can pull your trades. You may or may not feel comfortable with that. I haven't tried that yet (because I don't trade often) It has an interface where you can enter trades and transfers manually. It can also take a csv file with the proper formatting if you prefer that.

Mentions:#API

Crypto tax tools such as cointracking. API configuration is so simple that every non dev can set this up. Basically all trades get synchronized into your ray sheet.

Mentions:#API

Did you have to request the API from the exchange? I've never heard of that.

Mentions:#API

Paying a stupid amount of money for a service that does it for me. Was like $300 or whatever for koinly.... Petty goddamn lame, but hey, it worked with all my wallets and exchange API keys without too much tinkering.

Mentions:#API

US here and last year, it was actually much easier than I thought. Using TurboTax, they have a package you can buy which is just a bit more expensive, that will import your API keys from most exchanges. I was able to complete mine with only this package. Didn’t need anything else. Just TurboTax, email, and my exchange info.

On second thought I think this strategy might actually work, to an extent, due to self-fulfilling prophecy. It's the opposite of "If a metric becomes a target, is ceases to be a useful metric", If enough people use this MACD, then the will all sell ones the green line goes below the red line. which means the value of the asset will indeed go down as many are selling. same with the upwards trend. If enough follow, they all start buying and the value goes up. Rinse and repeat. Maybe that is even the whole point of this post. Make people use it will OP has a bot ready to exploit it? On some level I have a certain interest to create a bot that works over an API. But which exchanges have an API that allows trading on low volume and also allows getting these statistics? Will also be tricky to not be too reactive in situations the lines keep crossing.

I would mostly blame BGP for being sufficiently insecure to allow this kind of thing. But that is not a trivial problem to solve. Significantly RPKI validation would not have seen an issue here either. Some things that may have helped: - Stricter RPKI ROAs in terms of the ASNs allowed announce this prefix and the maximum length. No doubt Amazon had it looser to give them flexibility, but this kind of attack shows the downside of that. - Use of DNSSEC and a TLSA record may have helped browsers reject the cert issued by GoGetSSL. - Multiple server IPs / API endpoints from Cellar Bridge might also have helped, instead of hosting the entire service on one single IP.

Nice idea, you have to improve your coding skills and try doing this! You can actually call the API from the link I gave you, but still you need some coding skills to restructure the response to excel or something...

Except no, not in this case. Ledger failed securing a fucking public API. That has literally nothing to do with ”NSA” and everything to do with people responsible for security. So the question is: if CSO can’t run a team that is capable of deploying an API, what other mistakes have they made?

tldr; TL;DR: Coinbase Cloud enables web3 developers to build their web3 applications with instant and reliable read/write blockchain access using Node. By Luv Kothari, Group Product Manager, Coinbase Cloud; Sriram Raman, Product Manager, Coinbase Cloud Web3 development is complex. One needs to learn new programming languages, blockchain technologies, and on top of that, there are many protocols to support. Coinbase Cloud is committed to helping Web3 developers do what they do best… BUIDL. That’s why we’re taking our experience developing Web3 products for DeFi, staking and blockchain infrastructure and making this technology accessible for free to developers around the world, starting with the launch of Node. Node empowers developers to build and monitor their Web3 applications from an easy-to-use platform with instant read/write access to blockchains and powerful data indexers to speed up responses. Node, formerly known as Query & Transact, has been serving dedicated, paid nodes to enterprises for read/write access to 25+ blockchains since 2020. Since then, we’ve been listening to the developer community and heard a demand for a developer version of Node. Which is why we are launching a free plan for developers building on Ethereum, providing self-serve and instant accessibility to blockchain nodes via API. Additionally, we are launching new Advanced APIs to simplify querying the blockchain and powerful new NFT APIs to developers around the world. Node developer platform provides self-serve API access credentials, metrics dashboards to monitor and manage web3 projects, and developer resources to get started with web3 development. Node is available starting today around the world. We believe the most exciting projects in web3 are on the horizon and we can’t wait to see what the community builds! Get started for free. Coinbase Cloud makes it simple to build dapps. In addition to shared and dedicated nodes, Coinbase Cloud offers a fiat on-ramp with Pay SDK, trading APIs, Wallet SDK, and more. Our vision is to provide everything devs need to quickly, easily, and securely build amazing web3 apps.

I don't know how many "a TON" is, but you can import them into watch only wallets in Electrum. I've seen this done with a hundred or more address, it can take a while to sync them if they have a lot of activity. If you have like, thousands of them, I guess either batch load them into electrum wallets over time, or write something yourself to hit a public API somewhere (or your bitcoin node) and pull balances yourself.

We have a REST API that allows developers to easily integrate Bitcoin Lightning payments with their websites or apps. I can say 100% without bias that the user experience (both for the developer and customer) is much better with lightning than with credit cards. Just scan a QR code with your favourite lightning app, and the payment goes through instantly.

# Announcing MinatoPay.com [Minatopay.com](https://minatopay.com/) is a rest API that allows you to accept lightning payments easily and quickly. We support your privacy and don't ask to see your ID. ## Getting Started You can get started by creating an account at [app.minatopay.com/register](https://app.minatopay.com/register) and getting your API Keys. ## Documentation You can see [our documentation here](https://documenter.getpostman.com/view/23311215/2s7YzwomAB), we conveniently share a postman collection where you just have to add your API key to the environment variable, and you have access immediately. You can literally make your first API call in 2 minutes or less if you've used a Postman API collection before. # How can I trust you? This is something we thought about for a while and and also discussed with the stacker.news community. We came up with the following solution: As soon as we process a payment, it's available for withdrawal immediately, and for free (we pay the routing fees out of pocket). We prefer we don't hold onto your sats. Currently we support withdrawals of any size to [Wallet Of Satoshi](https://www.walletofsatoshi.com/) . Very small withdrawals elsewhere might currently not work due to the prohibitively large fees, but improving our capacity and connectivity is one of our top priorities currently, so that limitation is temporary. If you would like to make withdrawals somewhere and are not able to, you can let us know where you would like to withdraw to, and we can open channels there. # Our Feature Road Map * Improve our nodes capacity & connectivity greatly over the next few days (both inbound and outbound) * Optimize the prebuilt hosted checkout page, and allow you to customize it by adding your company/merchant name & logo * Add support for LNURL Withdrawals * Add automatic withdrawal option * Add fiat to sat conversion, so you can specify a fiat amount you would like to charge, and it will automatically be converted to a sat invoice. * Add some front end reporting such as seeing all your payment & withdrawal history in a table, seeing revenue graphs, etc. * Adding different permission levels for API keys * plugins for sites like wordpress and shopify ## Longer Term Road Map * The direction we are most excited about implementing is a non-custodial solution for [MinatoPay.com](https://MinatoPay.com). # SAT GIVEAWAYS This is just for fun and the amount is small so please don't take the giveaway too seriously. If you're selected, you can send me a bolt11 invoice (preferrably from minatopay 😉) ## Give away #1 10k sats for the first person to guess the inspiration behind the name/branding. ## Give away #2 10k sats for the most insightful/helpful comment

For the balance by date, I think we can get that one done easily enough. I think we’ll have something for that available soon. Value at the time of trade may be difficult, but it’s a common one that’s requested. So we’ll see what we can do. Total earned rewards may not be feasible in the near future. The issue is that most cosmos-SDK nodes do pruning. This means that historical data on each block will not be stored passed a certain amount on most nodes - and running your own node without any pruning is very costly. The dataset is enormous. We’re running a node with pruning and we’re already at 1.5 TB of data being used. In addition, to get good API performance from the node you need to run it on very fast NVMe SSDs, otherwise performance can be very bad, which leads to a bad user experience. Thanks for all the feedback though, it’s really great to hear. It helps us a lot to understand what people are missing so we know what to focus on.

A newly created industry of tremendous importance? To you perhaps. I manage global equity funds. SEC is the best enforcement and transparency across all markets by a huge margin. Standardized reporting, insider and fund holdings disclosures. Publicly available data API. Strong enforcement.

It's a world computer - literally. Replacing the entire IT stack and it's ludicrous costs and just building content that is infinitely scalable. A new way to run the internet and a true web3, all on chain, platform. Canisters serving web content that are smart contracts and on the same chain as your wallet. You won't go back to other projects if you really start to get ICP. It's that good and that far ahead. BTC direct integration has never been done, web content from chain has never been done, HTTPS API calls from canisters bringing off-chain data on-chain has never been done.

More generally, I think it's similar to BIP32 HD keychains (but not the same) And BIP47 is a minor variation of BIP32 The chess game is different to BIP32 * to generate a child pubkey, BIP32 increments an index counter and hashes xpub and derivation path, which includes chain code, and index * the chess game does EC point addition, adding the 256-bit binary number representing the chess move to the initial public key The chess README fails to properly explain the arithmetic which creates tweaked private keys for spending the coins sent to the tweaked public keys. The 142536/ADBECF analogy doesn't map into DEF being the 256-bit representation of chess move "g1-f3" (0x67312d6633) Perhaps I'm overthinking, and the corresponding private key is simply 0x67312d6633 added to the initial private key I suggest the chess game could be implemented using BIP32, and using the integer value of the chess move as the child index. The players would need to exchange xpubs at the beginning of a game Also, it would be wise to query the players' own nodes, instead of sending 40+ queries to the blockcypher API for each move

Not much, as things are getting expensive and available fiat diminish. Some ETH, MATIC, ADA, NEAR and API3.

It comes from the Coingecko API currently, soon it will come from PDAX and [Coins.ph](https://Coins.ph). We add 1% as our cut, but we may get more nuanced with that as well -- I'd prefer to offer the real exchange rate for buying bitcoin, to support stacking sats, and 1% for selling.

Internet Computer. Websites/canisters are dApps/smart contracts themselves and you can build anything on there and it's all on chain. No one has done this. Actual blockchain use cases with ICP and they haven't even released API canister calls to web2 API's or BTC direct integration (smart contracts for BTC). Easy transfer of coins for payments/donations/tipping through on chain chat apps, forums, video hosting, etc. All these apps are integrated on chain. No chain has done this or can do this. ICP covers it all. Not just defi scams as the usual chains put out as "development" dApps. <--- downvotes over here friends

Quant. Interoperability play like ATOM or LINK EXCEPT it's an API gateway meaning that it provides interoperability between blockchains but also to legacy systems like banks, etc. Partnered with Oracle, Sia, Amazon Web Services and others. Working on the digital pound, LaChain (Latin American dollar for I think 12 different countries). Less supply than BTC, but if you're against centralization or CBDCs may not be the investment for you. Out in front of regulation and will be a big player in terms of facilitating adoption. Not financial advice, though. Please do your own research to see if this is a good fit for you.

Maybe in the future banks will provide some options to buy/sell cryptocurrencies with them, hold your coins in exchange of "better security", more API if you leave your funds there so they can operate with them (like the fiat system but for crypto) etc. Being able to reverse transaction if you think the address was wrong and so on. This way people will be more likely to use day to day crypto and maybe will be more user-friendly but at what cost? Again you willing hand over your assets to the bank in which case she can freeze your account, block it or whatever she wants to do.

I manually collected onchain / exchanges data enough sample to be statistically significant, ETL into a sql server. Volume, price, velocity/trend/points of inflection, etc., all weighted, including sentiment (this is the subjective part) and externalities (ie. the recent merge). Fed it into a cloud-based analytics and got the number. If I keep getting close to actual numbers, I'll keep doing this and fine-tune and automate feeding data using API's

No A Core wallet is integrated with its node. It needs no index because it scans each new block to match transactions to the wallets' addresses. If a Core user imports a key with existing transaction history, he needs to run a rescan to find the existing history. Because there is no index for the rescan, it takes a few hours Similarly, if a Core wallet is lost or becomes corrupted, recovery requires waiting a few hours for a rescan Electrum personal server is another option for Electrum users. Similar to Core, it expects to build the transaction history as new blocks arrive, so it does not implement the indexes that ElectrumX uses. But it uses the Electrum server protocol for communication between wallet and Electrum personal server Some wallets query nodes directly using Bloom filters (but not so much because they're now deprecated) or compact block filters A couple of wallet developers created their own indexing systems and wallet -> server APIs. These wallet apps are dependent on their developers' servers Also, the different Electrum server implementations use different indexing strategies. One uses a mix of index lookup and compact block filters, and needs much less storage for its indexers, but is sometimes slower to find transaction history Some performance comparisons https://blog.keys.casa/electrum-server-performance-report/ There's at least one wallet which uses the API of a large commercial Web block explorer. The wallet app is very light. I have no idea how the developer pays for all the API hits used by his users

Strike does have an [API](https://strike.me/developer/) that can automate this process... I have personally set up the exchange workflow that I described above using [BTCPay](https://btcpayserver.org/), [BTCtransmuter](https://docs.btcpayserver.org/Transmuter/), and [Kraken](https://www.kraken.com/en-us). It is how it works for some lol. Merchants do have to pay exchange fees if they would like to escape BTC volatility by exchanging to a stablecoin when a payment is received. Kraken allows Lightning deposits, so there is no longer a fee to replenish the merchant's BTC balance. Exchange fees on Kraken are pretty low, much lower than 3%+$0.30 that Visa and Mastercard charge, so we've got that going for us haha. It is always free for the merchant to receive and hodl. It is important to remember that this is all very new technology. [Taro](https://lightning.engineering/posts/2022-4-5-taro-launch/) protocol will eventually simplify things even more, but it is even newer than the Lightning Network. Best part is that it is FOSS, so you can work to improve all of these deficiencies that you're pointing out!
