The defi hype is real but when we are talking about the real use case and there are some defi only with the real use cases while the rest only tried to follow the trend. As long as the that's legit defi with real use cases and it's always worth to invest in the defi but the problem is, are you sure to enter in the bullish zone? Almost all of defi platforms have gotten big pump.
I would think if it's good to invest in these defi platforms as long as you are taking the correct time to invest (it should be when the bearish trend happened)
