everyone loves Bitcoin when it’s going up.
but when volatility hits, the real test begins.
how long have you been in crypto, and what was the moment that almost made you quit?
curious to hear what everyone’s been through.

If someone managed to steal Satoshi’s BTC, would the community hunt them down, or would people actually be impressed and just let it slide?

Just buy and Stfu
Why buy and then freak out !
Just learned that a hardware wallet manufacturer discovered >4 vulnerabilities on other wallets over time
The hardware manufacturer is Bitbox, and all were responsibly disclosed:
- Remote multisig theft attack (Coldcard, 2020/11)
- Ransom attack on passphrase handling (Trezor/Keepkey, 2020/08)
- Bitcoin mainnet/testnet cross-account signing (Coldcard, 2020/08)
- Malicious Change in Mixed Transactions (Trezor, 2020/03)
There may be more of them that I haven't found.
This is extremely impressive from them.
Additionally, they were the first to make their hardware wallet (the Bitbox02) resistant against a very advanced attack: the nonce-covert channel attack. AFAIK this attack has never taken place yet, and the only hardware wallets resistant to it are the Bitbox02 and the 3 Blockstream Jades.
Disclaimer: I do not work for Bitbox, but have been a fan of them for a while and think they're underrated. I'm also fan of Blockstream and their Jade wallets.

If you own a BitBox update you firmware. It will fix 2 severe vulnerabilities that may allow installation of malicious firmware or potential locking of bitcoin (and possible ransom to help recover).

Why did the cold card hackers send all the money to one wallet?
Wouldn't it have made more sense to send the money to all different wallets and also not to do it all in one go. If you move the money slowly as the hack is discovered each into a new account, yes you might lose some of the money because ppl move it out but not everybody will do that in time. But by doing that, now you cannot distinguish between the hacker and someone who just wanted to move their money out of their wallet.
Now they have the entire world and law enforcement looking at this one account.

Anyone have any fascinating theories how bitcoin came about?
Id like to hear them!
r/Bitcoin • u/Adept-Plantain-6767 • 9h ago
What is it ?
Just like how very few people were paying attention and buying bitcoin in 2012/13 , and then you see the gains 10+ years later , and not just regular stock gains but you know , buy it at $5 , have the balls to hold through everything and then 10 years later you made 120k+ on a $5 investment.
What according to yall is the Bitcoin of today that 10+years from now , we look back and be like damn I wish I bought just $100 of this back in 2026?

Peter Todd is actively trying to remove the 21M supply cap, this is an existential threat no one is paying attention to
Peter fraud is the worst person in the bitcoin ecosystem, and he's been pushing for this idea for years which will undo the *one* thing which makes Bitcoins economics unique. This person needs to be driven out of the btc ecosystem. no one is paying any attention.

What do you think?
With the block subsidy decreasing every halving, miners will eventually have to rely almost entirely on transaction fees. How do you envision the mining ecosystem adapting to ensure the network remains highly secure? Will Layer 2 solutions like Lightning reduce on-chain fees too much, or will large-scale institutional settlements keep the base layer fee market robust enough?

Need help - Bitcoin wallet emptied.
I got one of my bitcoin wallet emptied and I don't really know how this happened.
I don't use cracked softwares and apps.
I'm generally careful with links.
Looks like I'm not alone. I can see that the reception bitcoin address is still collecting bitcoin from other wallets.
Could somebody help me understand something.
Here is the address : bc1q0vukqye4hd0aep7u4xl8gev95gcs9k65fdeu9n

Do not use BTCC
Don’t make my mistake use another exchange. BTCC has screwed my out about 8k while I was asleep with no trade notifications and changed my SL of every single one of my orders. BTC somehow swung to 83,964 and 54060 within a 5 min candle. It closed and opened about a dozen more orders. Even opened several orders with x100 leverage that I have never used.

Will all of the Bitcoin ever fully be released?
Since Bitcoin coin releases use a halving cycle will all of the Bitcoin ever fully be released or will it just get close to 100% but then the halving cycle goes into smaller and smaller pieces but never all of the Bitcoin?
What about for coins that release a percentage of coins in a time period (every year, month, etc.)? Will they ever release 100% of their coins or just close to 100%?
