Just what the title says if you have $50k fiat ,will you put on btc or in bank ,which of them will give you bigger profit after 10 years? Your money will gain interest when you put in a bank, your already sure the amount will increase, or put it on btc and leave it for 10 years. Which is better?
Profit wise, I'd choose Bitcoin although there are no certainties about it. Yes banks can give a sure interest in about 10 years but the amount of interest they gave are very low compare to the gains you can get if you invest it on Bitcoin.
$50k is surely a huge amount, why don't you just diversify it into different investments like crypto, stocks, bonds, real estate, business etc. Don't put 100% into crypto especially if you are not a tech-savvy guy when it comes to crypto. Don't do what other newbie investors out there are doing. They will just throw their money away and if they are at a loss, they will panic and sell and then argue with other people or saying "Bitcoin is a scam" blah blah blah.
