No, but like all speculation markets you can't predict the coins success.
I could have gone in on Bitcoin back in 2010 but I choose not to. Biggest mistake I ever made. Same thing with Eth. Could have gone in on Eth last year but I choose not to.
But yea I made $12k on Stocks this year.
It wasn't a mistake because there was no way to predict how it would be doing today. It could have been banned in between now and 2010 or crashed and not recover. Since the only use of bit coin is you can buy illegal things like drugs, guns, slaves, etc.
