I am not saying I expect a 50x return on my entire portfolio I meant that I will hold some coins that will give me a 50x return if I just hold them till peak of bull run over the next 6 months.
Altcoins can be very profitable if you get to risk your funds on the right coins but nonetheless altcoins unlike bitcoin isn't an investment you should hold for too long due to its pump and dump nature. 50x returns if achieved is a significant profit to be made though but hanging on altcoins in anticipation towards the bull run peak before selling or taking profit isn't anything I'll want to do because most altcoins may not even wait till the bull run peak before dumping and that's why it will more better to take your profit provided it has made some significant highs than waiting till your projected timeframe.
