All these hypes are just for them to make money and nothing else, as time goes by something new will pop up and everyone will move on, leaving DeFi behind, and also start hyping the new projects that comes out. There are good DeFi though, just dont choose based on how much they are being hyped, just calm down and look into them and choose whats right for you.
Everyone uses Hype defi to increase profitability because the increase is faster than other coins. On the contrary, they lose instantly due to rapid price movements. The hype defi opportunity is very good if it is exploited for profitability that is not too high with short-term trading.
