Why x10 is very hard? A lot of cryptotokens make x10 from previous year. The most famous are BTC, ETH, DASH, XEM, LTC, XRP. I think next year they can give x2 or x3 profit
They have done 10x last year, but I think it's hard to do this year. An investment can cost 10 dollars a dollar. But it's harder to get 100 bucks out of 10 bucks.
