As far as bitcoins in 2009 was just $2 dollars and bitcoins in 2021 is about 50,000 dollars there is no things that will make me not to forget it for that period of time as far as I'm still alive even with that I'll make all arrangements to make sure that my wallet is accessed even if I pass out.Laughs. Can you be able to forget your coins at the wallet for such kind duration of time?? If you can zero your mind, buy reasonable amount of coins and holdl till that time, surely you'll gain it a lot.
