HYPE is good for promising altcoins but can't say same thing for the shitcoin projects. There are several Squid or BabyDoge altcoin projects that pumped by hyped traders. Such mentioned altcoins shouldn't be traded before checking team members who ready to scam your last money.
^ I don't think it is a good and promising project when you encounter a hype coin.
Most of them are hype because of the traders not just because of their real use, it is very risky to invest and one day you will find out that the price has a sudden decrease of the price. We should be careful with the hype because anytime soon your capital will become down to maybe 50-80% if you don't know how to monitor it. I will rather stick on the coin that has a high volume in the CMC because I know they had an organic growth not just because of the hype. At the end, research and checking the whole team and should be the usage on it is very important to remain in a hype.
And it is possible that someone manipulates the price or like shilling by known personalities. But this hype is sometimes beneficial, we can make some profit on them, however, if we are also dumb not to think wise this also leads to huge losses. Well, a lot of people got into the trap, some just bought it on the last part, and after buying the price has just been in correction making them sell at a lower price.
Yes, research is the best way to escape from any think like this and we also have to keep in mind that not all the time the price is high, and that is why we should have an exit plan once corrections come.
