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 some of us I think its quite normal to go with the flow on the current hype in crypto. They take advantage it to gain profit, the problem is not all investors are doing their research before giving in to the project they want to invest, the reason why many investors are ending up losing their money for wrong decision. Thats why its better to invest in an old coin rather than in ICO, IEO or defi projects.
