DeFi projects are already on fire before bitcoin rise up to 10,000$, DeFi projects like COMP and Aave have already surge very high and this i believe is the reason why ethereum left it's 200$ boundary too
COMP and AAve has been getting a lot of demand even before the bitcoin bullish trend is coming right now. Both were getting a very huge demand caused by its usefulness as those projects have been taking the momentum. It's not the reason why ethereum gets an increase.
