There is a concern with Bitcoin Core versions 30.0 and 30.1. During the migration of Legacy wallets (based on the BDB database), in extremely rare scenarios, a bug may be triggered, leading to the accidental deletion of all wallet files on the same node.

Although the probability of this happening is very low, the consequences are serious, so a reminder is necessary. If you are using these two versions, there are two suggestions: first, make a backup of your wallet just in case; second, you can wait and do not rush to use the migration feature for now.

Bitcoin Core is preparing to release version 30.2 to fix this issue. Updating at that time will completely eliminate this risk. Safety first, no need to rush into potential pitfalls.

Even extremely rare events must be backed up; this is the first rule of the chain. Probability theory cannot be gambled with.

Damn, another one of these tricks. Are there so many bugs in version 30?

I'm a cautious person, but this time I really need to back up... I have to be careful with all wallets.

Wait, all wallet files are gone at once? That's too harsh. I won't touch these two versions anymore.

Whoa, all the wallet files are gone? That's really scary, but luckily the probability is low. Wait, what version am I using right now... better check quickly. Before version 30.2 comes out, it's best to stay put and not mess around. Backup, backup, backup.
