The best advice I ever gave to people was "buy $100-$1000 in Bitcoin and forget about it. Just put the wallet info in a safe deposit box and don't ever look at it."

This was back in like 2012, no one actually did it because they thought I was a dumb kid, but 10 years later they all came up to me and said "fuck, if I listened to you back then I'd have $5M right now". Since most of them only read WSJ and shit, so they wouldn't have heard anything about it till it was worth a ton.

BTC has always been a bag holding scam, but if you had the cash to burn it was definitely a fun gamble to make.
