It depends to what kind of hype you are referring to. If its the hype coin then its risky man. Yes you can gain profit but not for long term. You cannot put forever your money there. You just go with the flow of the coin's hype being driven by whales but be careful in going out and sell at right time also.
Literally all altcoins are being hyped, the only coin that does not get being hype are stable coins, because hyping does not really affect its growth. Like you said, hyping is good, but we have to also study the type of hype it is.
Hyping has really made a lot of people rich, especially the ones done on these cheap shitcoins, if hyping successfully get them to bull run, the profit the investor gets is almost 1500% of his initial investment, but hyping could also back fire in a big way, if you can the hyping at the tail end when the dump will occur, then it will be to the disadvantage of such investor. We just have to know how to play smart in this market.
