Cryptocurrency is a real business. If you have the support and the expertise to work for yourself, I think you should do that. You will create work for yourself and even for others. The idea of being an investor and waiting to collect your winnings is not an idea with which I'd be comfortable. Investing is something you do when you have a bit of surplus money. Common wisdom tells us we must only invest money which we feel we can afford to lose without altering our lifestyle. So there's my bit of advice, FWIW. And I do wish you well.
