The only issue I see with crypto is that there are so many platforms popping up daily, how do you decide which one to choose from. I.E. Bitcoin is the Gold standard but you also have Litecoin, Ethereum, Ripple, Steem, etc. I would love to buy Steem as it's still cheap but it seems to be a gamble to me.
At some point, I anticipate these smaller guys will crash because I don't see businesses taking hundreds of crypto currencies as a form of payment. While I know Bitcoin is the standard, something is going to have to give to make this a legitimate worldwide currency or there needs to be a better inter-exchange market available.
