There are rumors that "Bitcoin can be cracked by quantum computers in 9 minutes"? Pure nonsense!! Everyone stay calm, the market also shows that it's not a big deal at all. Currently, all quantum computers, including Google's, are still far from posing a real threat. This is mostly theoretical speculation in papers and cannot be practically implemented. In fact, Bitcoin has been called out multiple times in its history as being "crackable" or "going to zero," but each time it was just a false alarm, and the outcome was very clear. If you're holding BTC and worried about risks, just transfer the funds from old addresses or public keys that have been exposed to new addresses—there's no need to worry about anything else.
