For me the best one is BNB now. It seems like it has the highest potential among other altcoins. BNB has come a long way in a very short period and reached an ATH at $342. But this is only the start I think. My expectation from it is really big in this year. We may see the price reaching even 1k dollars before the end of this year or a value between $500-600 in the worst case.
BNB can easily make 2-3 x, but then, with such activity in the market, with a bullish trend, everything is growing very quickly and even 10 x per coin does not seem like something magical, but quite ordinary and acceptable, so I do not even know.
BNB is not the best option, I think.
the biggest part of my money in bnb now))) i hope to see x2 in upcoming week and then invest it in another coins like ont,eos, trx, 1inch, sol, srm.
