What are the chances that these wallets are actually broken by bruteforce? I know there were discussions some years ago about people that were trying to crack the private keys.
What do you think guys? Can such successful act would mean the end of btc era?
If you can find proof that it is successful private key brute force, you can say it's the end of Bitcoin blockchain because even you use a non custodial wallet, has private keys in your wallet, you don't control your bitcoin. Someone else can find your private keys and use them to move your bitcoin.
So far, no proof to say about it so let's assume Bitcoin private keys are safe if you use a non custodial wallet and has good practice when create your wallet, offline or best on air gap devices.
