ICO, IEO and now DeFi.
Have you seen that none of these are long existing? ICO created hype back in 2017, then IEO come into the ground and now it's time of DeFi. But with all of them, a lot of people were attracted and get scammed. It's not that easy to make money, dude. Don't run after anything which creates significant hype. Take time, observe and make decision. You have enough time to make profit.
The positive of the hype is we can get easily money for it, but the negative side is also we can easily lose money on it. I believe without any hype will create a good condition, but I think the hype is hard to get rid because of many people greedy for profits. So the answer to the hype situation is himself, whether he wants to join or not. For me, I would stay away from any hype situation, because we don't know which one will get profits or loss
