Guys, specially those who have been in this crypto world for so many years, kindly share your views on potential 10x altcoins in next Bull run ?? 
It is hard to make predictions about Altcoins that could increase prices as you mentioned. Because the return from Bitcoin is only just beginning. If we observe on coinmarketcap the Altcoins price increases very slowly mainly Bitcoin increases in price. Not entirely like that, there are some alts whose price has gone up very fast. But always make sure to buy it at a low price, don't let the price go up by about 30% - 50% you just bought it, the risk level is very high.
The risk level is too high if you don't have any idea from those alts that you'll going to buy, you need to have an in-depth understanding not
just fomoing and trying to ride along, alts have good potential as most of the traders use this market to divert their earnings after gaining
from bitcoin market.
