It is possible,all you need to do is to find the underestimated cryptos, and hold them.Good luck bro.
These days they are very difficult to pick.
It seems that unless you are really lucky you aren't going to easily find a 100x coin but most likely a coin that will go bust or make very little profit.
Seems the only ones that make decent gains are only in the 2-25 of CMP range and those are already expensive to buy
