I too bought in heavily to the precious metals craze in 2011 or so. The world was full of doom and gloomers and I was going to make a fortune! The problem with precious metals is to make that fortune you have to pray for world anarchy (Zombie apocalypse). With crypto that is not the case as the newer more efficient currencies are starting to be a faster, cheaper way to do business and not just a store of wealth. (my own personal experience of this is the difference between using crypto to send money overseas vs going down to my local bank. You will lose at least $20 and your mind doing it!) My parents would certainly have understood that.
I am 50 and I keep my gold and silver and grow my crypto balances by converting paper into crypto. I think both have value but for different reasons.
