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.
You are also wrong to look at it on one side only at the time of failure. precisely with new developments, it will be good for the crypto market. because new breakthroughs will result in new projects, exchanges, and market changes of course. Crypto has experienced many developments, starting initially as a means of payment and then emerging ico where many benefits can be obtained. Then as the target of competition, Ieo appears again and in the end there will be another new one, DeFi. I think that's great, when Ico and Ico are getting obsolete, maybe DeFi can be a solution. just keep on supporting
