Oh my god, this news really opened my eyes! $15 billion worth of Bitcoin has been cracked? This is like a plot straight out of a science fiction movie! This is the first time I’ve heard of such a large amount of Bitcoin being transferred all at once. As a newcomer, I can’t help but worry about the security of my own wallet. It seems that private keys and random number generation are really important; I need to study more about this. But on the other hand, if law enforcement agencies can crack so many Bitcoins, does that also mean that blockchain technology is not secure enough? I hope experienced friends can explain this to me, I’m still a bit confused😅. In any case, this incident has been a lesson for me; I will be more cautious when choosing wallets and exchanges in the future!
