Everyone forgets that for their investment to be a success they must get back their principal and on top of that a little extra. It is just like buying investment insurances where you put in a little bit each month and hope for a payout it matures.
Buy and hold for cryptos looks the way to go just like stocks in the early days. People can invest in other ventures but just don't go all when "diversifying".
@marcusxman I agree just buy and hold and you will most likely get a ROI just doing that and nothing else.
