Defi is still Alive but the thing is are they still competent in market growth?this is the much important question to be answered.
Looking towards the Defi Projects that made a real Huge run last couple of months? i think what you asking is True and DEFI may not be dead totally but this is dying now and won't be able to come back like what ICO season does years back.
Look how they perform in this Bullish market?
While the majority of currencies are Pumping Greatly yet DEFI's only goes a little Green and Red at the same time.
I also monitored this ,i was expecting more Pumping from their end because Defi started this bull couple of months ago before the XRP followed and then EThereum and Bitcoin.
But seems to be no in this direction defi is facing.
