thanks a lot for the advice.
I think there are some things that need to be done, such as telling confidants or close family members because we all don't know when we will die, it's a shame if we close everything ourselves without anyone knowing, when we die suddenly the asset doesn't exist. 1 more person who can take it, very unfortunate in my opinion. Therefore, I think there must be one trusted person and the best is our own brother who knows everything about what we store.
other points very good advice. we do have to take care as best as possible to avoid bad things.
Yes we must have to tell someone because as you said one day we may be no more and if you don't disclose to someone, we just have our coins registering as lost coins. Likewise today it is already happening like we see some wallets having lots of btc that we suspect the owners not having access to them again. The people we can tell are those close that won't scam us like next of kin. Keeping coins only to ourselves is not the best. We can include the password in the will .
