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.
For me, there are 2 types of people who jump into hype. There are one who think that the coin is good because of hype and trapped, and the other who really want to take the risk to join project that already hype. More important to make people concern to learning first so the first type that i mentioned before not keep losing because maybe it can affect to whole crypto community.
