On the occasion of what a colleague of the local forum said, and that I translate to you:
I mentioned not long ago how a friend of mine lost half a Bitcoin by saving it in a wallet on his cell phone, and since he opened it with his fingerprint, he didn't think it was necessary to copy the seed, not even the wallet's password. Until some update asked him for the password and he is still looking for a way to find it out.
I wanted to ask you if you know of similar cases in recent years.
We all know that in the early years a lot of bitcoins were lost because they were worth pennies, most people didn't even imagine where this could go, there was no HW and things like that. But even though the bitcoin loss rate has been reduced in the last years I am sure there will still be human errors like the one in the quote that will end up with bitcoin loss, which is not bad for the rest because as Satoshi said they are like a donation.
Do you know of similar cases?
App wallets usually have an update system and if your friend misses it without saving the recovery seed it might be difficult. For example I use the Trustwallet wallet where at first they had not implemented the fingerprint system, it still used a combination of passwords. Your friend case seems almost similar but the strange thing is if he does not save the recovery seed it will be difficult to access the wallet because it only relies on fingerprints without covering it with a password.
