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.
But some people also have the success, the smart people make money, while those who are not making a research they will fail in investing.
It's not the fault of ICO, IEO and now DeFi as there are legit projects under this, it's the fault of some investors who failed.
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.
Hype is useful, without crypto hype, bitcoin would not be popular, remember 2017, bitcoin got its ATH because of hype.
