If it was one of my friends I'd tell them to get a brain surgery or something. It's one thing to forget a password and another not to have it written somewhere. He's an idiot for holding all his coins in one place and not even remembering a password. Like what more important things do you have to remember than a password to your 200 million dollar wallet?
LOL.. he is having difficulty in remembering one password, and you are recommending him to have multiple wallets and separate passwords for all of them? To be fair, he received the coins in 2011, when the exchange rate was like $0.10 per coin. No one really expected Bitcoin to rise by 400,000x in just one decade. You may hear similar stories from a lot of users, who received their coins in 2011 and 2012.
