BTC

Sprunklefunzel

Bitcoin is not crypto. TA is 100% BS. Nobody knows shit about fuck when it comes to market/trading. MACRO is informative but terrible at timing. Prefer owning your own BTC but unless you have specific needs and up until a certain sum, buying an ETF is fine. Just HODL. Ignore influencers. Their interests are not aligned with yours. Bitcoin is disruptive tech. People are afraid of change and will fight it. Spin up a full node if you can. Never invest more than you can afford to lose. BTC is the best form.of money ever, but this does not mean humans are smart enough to realise this and not take advantage of Satoshi Nakamoto gave us. Never advertise how much BTC you have, nothing good ever comes from doing so. Don't push BTC ideology on to others but explain and educate those willing to listen. Hold tight! It's going to be a wild ride.

??? BTC got that popular just because it supports money laundry (and tax evasion)

Effective_Engine319

A few years ago the Canadian government froze the fiat accounts of protestors who protested for the wrong political party. BTC is inherently censorship resistant. Implementing bans on coins of people you don't like breaks that.

BTC HODL DCA rien de plus

Page_Unusual

Mix thousands and thousands times, then spent. Yeah it all trackable, but NSA wont bother with your 0.1BTC stolen.

Or1001

This post is horrifying. Imagine following every single opsec rule, using 3 separate air-gapped Coldcards, and still losing 18.25 BTC in 8 minutes because of a device or firmware flaw you had zero control over. This is why pure self-custody is a massive risk for real wealth. Your security can be 100% perfect, but you're still relying on a $150 plastic hardware wallet not having a supply chain or RNG bug. With institutional custody, you get actual multi-sig vault infrastructure, legal recourse, and insurance. "Not your keys, not your coins" sounds great until a single vendor bug wipes out your life savings.

BTC up.

Febos

Now and next year is good time to buy Bitcoin. Best to buy every month. You don't need whole BTC or $20000 to buy it. Just buy as much as you can.

Remyglr

Rien que cette inaction qui relève pourtant du bon sens couplée à une démarche de transparence démontre l'opacité entourant le système bitcoin en général. Le BTC c'est le far west du 21eme siècle.

Captain_Spaceturd

Excuse my complete ignorance but why are there still people vulnerable to this? Wouldn't there have been an enormous run on Coldcard to empty wallets on day one? Like, does everyone have notifications turned off? Lost the keys? Just I don't even own BTC and I know all about this. It's been a week - just a bunch of HODLers out in the Canadian wilderness chopping wood?

crunchyeyeball

They're only "real" addresses in the sense that they meet the checksum requirements. Nobody actually has the private key though, so anything sent there is lost, hence the tiny send amounts. E.g. the address: 1111111111111111111114oLvT2 ...is a popular "burn address", holding 800+ BTC.

harpocryptes

> This is still theoretical and nothing to be concerned about. Modern Bitcoin transactions hash the pubkeys. However, millions of BTC are still in these old adresses, not in the modern ones. It's very much something to be concerned about.

AlamoSimon

What does anything of this have to do with the US? Why would the BTC go to the US?

sht-magnet

I mean the cheaper you buy the better. You buy your fav chocolate from the supermarket, next week you see a 50% discount, you’d buy even more than usual, so when the discount is over, you still have cheap chocolate in your fridge. I genuinely enjoy being able to afford more BTC with my regular DCA amount. I remember going crazy when we went down to 20k, I was almost 50% in red, but kept buying to reduce avg. now we are deep in bear market, thanks to that period, I am still in profit with a good margin.

BigDik6355

I wouldn't be so sure to make that bet to be honest. FTX, Celsius, MtGox, QuadrigaCX, Cryptopia, BTC-e... the list of exchanges that went under is long.

Guy_Incognito97

For most people it will be 18% tax above £3000 profit and fees are negligible. That’s roughly the same as the US where most people will pay 15% on all profit. For a short time you were allowed to hold BTC via ETF in an ISA and pay no tax but that was removed unfortunately. Hopefully it is reinstated.

userdeath

Poor guy never did the research and thought the minimum buy is 1 BTC 🫠

Prior_Parsley3960

summary for those of us with adhd brains Researchers now say they've identified the developer responsible for the flawed randomness code behind the ongoing **Coldcard seed-generation vulnerability**. The report claims: * The vulnerable `libngu` code was authored by **Coinkite CTO and co-founder Peter Gray**, based on cryptographic GPG commit signatures. * Bitcoin developer **James O'Beirne** says he warned Coinkite about the randomness issue in **May 2025**, but the warning was allegedly dismissed. * Coinkite has **not publicly responded** to the identity allegations or the claim that it ignored the warning. # The vulnerability * A **single code change in March 2021** accidentally replaced the hardware random number generator with a weaker software source when creating wallet seeds. * The result was **far less entropy** than intended, allowing attackers to regenerate affected wallet seeds offline. * **No phishing, malware, or physical device theft** was required. # Current impact * Approximately **$114 million (≈1,800 BTC)** has reportedly been stolen. * More than **5,200 Bitcoin addresses** have been compromised across four attack waves. * Coinkite says the exploit **is still active**. # Who is affected? **At risk:** * Mk3 wallets initialized on firmware **4.0.1 or later**. * Mk4/Mk5/Q wallets that generated seeds **before** the patched firmware releases. **Not affected (based on current reporting):** * Wallets created using the **dice-roll seed generation** method. * Wallets protected with a **strong BIP-39 passphrase** (risk significantly reduced). * **Multisig** wallets where the affected Coldcard is only one signer. # Bottom line This is becoming one of the **largest hardware wallet security failures** in Bitcoin's history. The immediate risk remains the flawed seed generation—not the hardware itself. If you ever generated a Coldcard seed on affected firmware and haven't migrated, **move your funds to a newly generated wallet immediately.**

Upper-Media3769

You know you don't have to buy whole units, right? It's not a physical coin. Start DCAing with an amount you're comfortable with on STRIKE or something like that and get a Trezor wallet with a strong passphrase to store your BTC.

Kitchen_Play_8123

I'm a banker, so I believed in real money, CDs and low risk assests and I simply did not see a BTC hit over $100k one day, but...It did and I know lots of ppl gaining from that. In fact, my partner has been sitting on 5 btc since 2023 and has no plans on selling it in the near future..If you go to Europe they do real estate transactions in bitcoins.

moviemaker2

> A hardware wallet’s most important feature is not its seed phrase creation, it’s just a convenient feature. The 'boom' you hear is the moving goalposts breaking the sound barrier. I've been active in crypto for about 14 years. I have never once heard someone say creating the seed isn't an important part of a hardware wallet until this week, when all the Monday morning quarterbacks came out. In some sense it's the main purpose because all other ancillary purposes, like signing transactions, are contingent on the existence of a wallet. Last week, any person doing due diligence to self custody their coins in a safe way could have reasonably landed on a Coldcard as one of the best solutions, along with the TRNG being sufficient for 256 bit entropy. Dice rolls and passphrases were considered extra security, above and beyond the sufficient amount. For most of the last 5 years, the other highly recommended HW wallets didn't have dice rolls as an option, their on and off device RNGs were also considered sufficient. This is the first time people who didn't do anything 'wrong' in the self custody process have lost BTC. You can argue that they didn't take the maximum conceivable number of elaborate precautions, but no one really does.

ICantWatchYouDoThis

if you didn't trust it back then, why do you trust it now, when the coldcard incident just screwed a ton of people? not trying to be rude, I'm just curious what the average people think about BTC's trustworthy now

Tedious-Butcher

Ran out of btc. No worries. I paying a lower level thug in ETH to slap that person of yours that slapped my BTC contractor.

Azurebbit

Odds are they didn't do it. They would never be able to retrieve and use the BTC without getting caught. Even ceding the point these might not be the smartest people; that's like a cashier stealing from their own register. There are (were) so few people at Coldcard, all the employees are going to be looked at hard. Stupidity and negligence are by far the most likely scenario.

Present_Let2487

If privacy is your priority, BTC probably isn't the best choice. I'd go with TRX from the options listed, low fees and no need to deal with stablecoin networks.

immersive-matthew

This is almost certainly what they have. Unsure why more do not go this route along with Tails OS air gapped whenever they move BTC.

Dimasfadz

No one knows if it's the best time. I'd be more worried about buying 1 BTC on day one than the price itself. Start mall or DCA first

omni_wisdumb

I never said BTC addresses can be frozen. Y'all cannot read. With that said, unless the coins are obfuscated using a system like Monero or Tornado, coins can be tracked and if they're ever onloaded to an exchange, be frozen. But again, I am not saying that happen. I'm literally asking how the OP has concluded there was a "blunder".

HeroicHeron

That's likely true, but only because of how many people lost their wallet.dat files or passwords in the extremely early days where thousands of BTC were easy to get, but worth mere cents. In terms of purchasing power at the time of the loss, I'd bet the opposite was true.

SuckinAwesome

If your first question about bitcoin is it's price prediction then it's probably not a great asset to buy at this time. If you're convinced by the 'Why' of BTC then it's a great asset to buy.

GenderJuicy

Do you guys really look at the price of BTC and think "I don't think this will ever go up again in the future"?

kardanokid

Putting all thr BTC in a single address that now will be blacklisted... n00b mistake. If it was him, he coulda got away with it... now, he's fuuuckdd.

TwinWake

As long as you can “buy” BTC.

MrSnugs

Really unfair statement. Users of ColdCard tried to do the right thing to keep their BTC safe. Coinkite the company absolutely failed them.

scrandlle

Not a single person can answer this question with any real degree of certainty. There are very little market trends to look at unlike traditional investments. There's no quarterly financial reports from a publicly traded company. BTC isn't used for anything like gold is. Whatever you would hear here, good or bad, is merely a guess. Probably an uninformed one. If you're a bit of a risk taker, BTC isn't a bad thing to speculate on. If you traditionally go into low or moderate risk index funds, BTC probably is not for you.

devCheckingIn

Jim Cramer selling all of his BTC. Good or bad?

TitanicChurro

The best time to buy BTC was in 2009, the next best time is right now.

OkProject2361

Yes, very easy to navigate for anyone that’s ever used any crypto exchange to send/receive BTC. I wouldn’t buy there though, the price slippage + 1% transaction fees on the one buy that I made with them was too much. I’ve been a River user for a while. I’d continue to buy there and send to the Fidelity wallet.

IRushPeople

So why are they selling then? Saylor is on record saying that the plan is to buy and hold the BTC, never sell, or you erode trust

danxtptrnrth1

Same. I also like their supercharge feature for recurring buys. I have a weekly recurring buy set up. On weeks that BTC price is down, it automatically doubles my buy. You can set the supercharge to 50-200%.

Faile-Bashere

Jokes on them. I got scammed out of my 4 BTC back in 2014.

b1mm3rl1f3

Imagine being asked when BTC is down 50% YoY lmaooo

fberbert

The project is educational. I clicked on "verify my seed," and it scolded me, saying I'm the weak link. It then gave me tips on how to store my BTC properly.

JimmySki6166

BTC, the best thing you can purchase! My first BTC was 12k, it’s 63k today. Made a lot of money 💰 with BTC and will continue to to so

MorninggDew

Anything for some BTC bro 👊😅

mrjune2040

And I’ll pay someone in BTC to slap the hell out of them.

JimmySki6166

I have been purchasing up to $500 weekly of BTC for over 5 years now. You can never have enough, and when it’s at 200k, you’ll look back and know you made the right move!!

definitely_Hareb

If you want lowest fees and privacy, BTC is the worst option here. TRX network fees are basically nothing for USDT transfers, like a few cents. For the no-KYC part, just use any swap service that doesn't require an account to turn your euros into USDT TRC20.

a10ondr

Anonymizers, mixers,... You can track it now, sure. What if the attacker sends it to a big common wallet (mixer) which has all sorts of incoming legitimate transactions. You just lost your trace, now you see one big wallet with a 1000 BTC and you can only blindly guess which outgoing transaction is the attacker's one (can be tomorrow or months later).

Professional_Track95

Been using them for 3+ years. No issue. I park my saving in there for 3.3% return in BTC. Eveything is fast & reserve verifiable.

Han_Gabrell

I like that perspective. Do you think Satoshi would appreciate some of the newer ways people are putting native BTC to work today?

Han_Gabrell

It's cool how your focus shifted from the price to understanding Bitcoin itself. I think that happens to a lot of people who stick around, especially as they start exploring what else can be done with native BTC.

Nullius_123

One upshot of this debacle will be more people buying ETFs rather than holding their own BTC. The custody of BTC will likely be the next area of regulation. Expect the banks to play nasty.

Time_Basis2535

Every day is a good day to buy BTC. It happens to be on sale for 50% off

Han_Gabrell

If you're already looking that far ahead, short-term volatility probably doesn't matter much anymore. It's also nice that there are now ways to make use of native BTC while still keeping it in self-custody.

sonofliberty1765

River is great. They show their "proof of reserves" every month verifying the BTC they claim to hold is actually there. They're constantly innovating/improving the platform. The fact that they're BTC only is another reason that makes them a great choice as an exchange.

pantuso_eth

If your personal investment portfolio includes just one asset, you expose yourself to concentration risk. Diversification is the standard way to mitigate concentration risk. If you sell all your BTC to buy AAPL, you haven't addressed that risk.

AccordingFloor7010

But the BTC guru, Saylor, buys high and sells low.  He just sold this week.  So shouldn't crypto bros follow his lead?

Alphamale822

You can’t crash BTC with just a few 1000btc

Easymacsauce

I use them to buy and sell BTC. It’s my favorite exchange.

Possible-Mud-1380

Lol. I mean, it's possible. Maybe China thinks killing BTC will pump gold?

Vagelen_Von

The first moment I heard about the hacking I thought that price of BTC will drop to 5000$. So just a theory for experts to examine: Big banks and conglomerates fund secretly a tech company to develop a faulty hardware wallet. Then steal Bitcoin from users and have many successes at once: 1) defame all the self custody idea. 2) make users paranoid for cold wallets. 3) earn a lot Bitcoin with a few millions of investment. 4) panicked users run to buy ETFs and other hybrid products with fiat money. 5) having a good big supply of BTC in case make something like gold standard with BTC in the future. 6) promote the idea of semi-custody. Half private key for the user and half for the bank. 7) obtain knowledge to break other companies' cold wallets not only tech knowledge but also operational knowledge to infiltrate in tech companies and do damage. So people who affected and all the crypto world should carefully examine: > How exactly company funded? > Relationships of everyone with big banks, former employments? even family relations. > How law enforcement handles the situation? Who goes to prison. > Future careers and wealth of everyone implicated and their families. Etc etc

FuturePrimitiv3

They have no interest in BTC other than how they can profit from it in the short term. It's just another scam to them, nothing more.

Skinny_Human

Right exactly. My big dilemma tonight is do I cash out or continue to hold until BTC climbs again knowing that there’s a good chance more hacks of some kind are on the way

bhalter80

To be fair there has been some high profile floating from the BTC community about its meteoric rise like any investment vehicle or get rich quick scheme There's been a lot of good tech to come out of it too

Beginning-Editor182

🤫Les gars le BTC a déjà touché son plus bas et c'était le 1 juillet

Super_Weekend_4428

Eh, I don't know. I still have some but I've more or less lost faith in it. It doesn't work well for payments. Transaction fees are nuts. It doesn't work as hedge because when the market tanks BTC does too. You are probably better off buying an index fund or something.

magma_lakes

OP is referring to vulnerable ColdCard BTC that remains to be stolen. A benevolent group could race the attackers to brute-force remaining wallets, empty them, and somehow return the coins to the rightful owners afterwards (as OP's theory goes).

Possible-Mud-1380

Or they don't care of they're caught. Or the primary goal is to fundamentally call BTC into question. Both of those align with potential nation state motives.

frozen-sky

I generated my seed on my laptop. Not airgapped. Totally insecure. I always was planning to move to coldcard, but didn't come around it. Seems my procrastination helped me here. Last year i decided to leave BTC completely instead. I don't hold anymore It is devastating to see so many people with lost BTC, collected with DCA or whatever. I count myself lucky. If i would reenter the game, this episode would definitely adjust my strategy. I would probably choose an airgapped computer with USB boot or something. And a stupid game to create entropy. Or role dice. I would probably refrain from hardware.

Due_Difference_1412

I agree that SOL probably has more upside than BTC and ETH. However, its volatility and unpredictability are also much higher. Network stability, ecosystem competition, and overall market sentiment can all have a significant impact on its price. For me, investing isn't just about chasing the highest returns—it's about finding the right balance between risk and reward. That's why my current focus is on short-term futures trading. I prefer to manage risk through strategy rather than relying solely on the long-term potential of a single coin

devCheckingIn

BTC is back to trading like digital gold.

Downtown_Ship_6635

I suspect Satoshi was really a good guy and created each new wallet without storing the keys. If you do not want to access the BTC later, security becomes much easier...

bananabastard

There was a thread on here a day or so ago with someone going through exactly this. He knew for 3 days that this hack was in play, and he was watching his wallet, waking up every day and checking. His BTC was still there, still there, still there, and then, gone.

FuturePrimitiv3

😂 no down vote from me! I'm not a BTC "true believer", just a nerd who thinks the technology of BTC is interesting, but still struggles to find a valid use case.

UtahImTaller

Crypto has been pretty doom and gloom for the last few months from what I've been reading here off and on. People legitimately think the last bull run was the last big one, and that altcoins and BTC will never see the mountains of returns we've seen previously.  That, to me, is very bullish. My speculation is that it's a great time to buy, but I also could see why people believe people altcoins (not necessarily bitcoin) are dead. Especially since crypto in general is very much based on speculative value and almost zero use case. Obviously outliers exist, but that's my take in general.

Nymister

In three days time, will be the best time to buy BTC. Mark my words.

theincognito66

if everyone sold all their BTC and only bought the ETF, this entire asset would collapse in value. Read the white paper - we are trying to own something that banks and governments cannot control.

Nick700

Unfortunate for those who gambled their emergency fund on BTC otherwise who cares BTC/USD is up 1300% in that same timeframe USD inflated 25%

Fluid_Ad8452

This is so cool, very cypherpunk, I love it. I don’t own a N64 but I saw a similar project for GBA and BTC so I might as well try that one. One thing worth nothing is, the novelty here is the device used to generate which was built on the pre iot era, giving it the same level of isolation than the ones of devices that were designed today **with that objective in mind.** Same security vulnerabilities could be found here as the CC wallet because that depends on the RNG algorithm they decide to use, I assume controller input, sensors which should be validated are still working properly before using them as entropy source, PRNG etc. The key here is scrutiny, which is something CCW didn’t had until bad actors took a look. But this is the monero community after all, so this is in good hands. Thanks for sharing!

Soul__Collector_

Care to name some.. Because taking the loan then moving the BTC seems like the simplest rug in history

InsightKnite

They both have some of the lowest multipliers in terms of return. Neither of those coins are getting more than a 3x and that is absolute best case scenario. Hell even SOL can hit a 4.5x on it's best day. A far better ROI than BTC or ETH.

moviemaker2

>nothing about the seed generation is changing anything about the capabilities of the device to hold my keys "Sure, one of the two primary functions of this device was shown to be incompetently implemented to a staggering degree, such that almost a hundred million dollars worth of BTC were stolen off devices whose sole purpose was to secure that BTC. But trust me bro, there's *no way* there could be any undiscovered vulnerabilities in the other primary function of this device. That would be just crazy. They pinkie-promised it was just that one." >pls explain exactly why and where there is potential danger This is why I asked if you get scammed a lot. If it has to be explained to you why using a coldcard is dangerous at this point, then you are not good enough at risk assessment for it to be worth the time.

Skinny_Human

I had a cold card so I sent my BTC to one of the big exchanges and made it as secure as possible using 2FA with an authenticator and a long password etc I think it depends how much you have dude. If it’s a small amount leave it where it is, if not, do what I did My dilemma now is worth to cash out or hold. I think we’re at the point where self custody is becoming too dangerous to be worth it anymore with the Advent of AI et cetera.

LeMAD

This is the final straw for me. QQQ +7.25% over 5 days, BTC -0.94% over the same period. Crypto is officially dead. It has been fucking garbage in the most incredible bull market in history. There's no runway left. Any sign of the beginning of a bear market will send Bitcoin below $10K.

drwebb

I mean no ones knows, but I prefer to believe Satoshi is alive and just has the op sec on the level of the creator of BTC.

EnvironmentalYard467

For sowm reason I doubt that. Trump and his sons have a shared interest in BTC, they worn allow anything that prevents that interest to hurt BTC. Not because they care about us, like I said they aren't going to pass something that will hurt their pocket books.

N22-J

I think BTC could go up, or down.

Vinny_d_25

I doubt there would be accidental collisions from legit cold card users. I can't say for sure without knowing the full details but given that the timestamp and deviceId were part of the faulty entropy, on first glance it seems that duplicate seeds would not be generated under normal use. I was wondering if someone (or multiple people) figured out the exploit some time ago but chose to only take from a small number of wallets to not raise alarm bells. If a hacker takes from one wallet, most people would probably thing they exposed their keys somehow and it wouldn't be high priority for the authorities. With the current situation, the hacker is going to have a hard time cashing out that BTC and could be caught if they make any mistakes.

Jayrovers86

Hundreds of thousands of BTC has been lost/stolen by CEXs why would you think a CEX is a safe place to store BTC.

gfry35-

Welcome to Bitcoin. My advice as a beginner: don’t rush to buy 1 BTC all at once just because you feel you’re late. Nobody knows the perfect entry point. Start with an amount you can afford to hold for years, learn about Bitcoin, and consider buying gradually (DCA) instead of trying to time the market. Also, don’t put money into BTC that you might need soon. It can drop 50%+ and you need to be comfortable with that. The best investment is the one you can hold through the bad times.

CoincidentallyTrue

The best way to cash out on the heist would be send it to a series of real users who then proceed to “wash” the BTC.  For example, a private VPN service provider that offers VPN service to the hacker in exchange for BTC (these exist).  The provider then proceeds to cash out the BTC.  If questioned by the authorities, the VPN provider can simply state they were offering an anonymous service to an anonymous user and not breaking any laws for doing so. Once the authorities stop looking, they proceed to funnel the cash back to the hacker in exchange for a very decent commission. 

Big-Cheetah5159

First, there is no such thing as tainted bitcoin. That’s just a label created by the government to promote a negative outlook on Bitcoin or “criminal money”. As if the dollars in circulation aren’t used illicit activities by criminals worldwide wide. To answer your question, nothing. They can’t make the wallets that received the funds do anything. The same way as if you send BTC to the wrong address, you lost and the got free money. On contrary good hearted people would send it back to the original ones who had it stolen. This is a decentralized network, there are no rules, no laws, or no protection .

Ledger is VC backed, which does boost its credibility substantially. I just wish people can covert BTC to ETF shares, then no one would have to worry about cold storage bullshit.
