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.
