In my opinion yes. Bitcoin is the primary cryptocurrency and all new investors that will enter DeFi will surely buy first bitcoin before they start buying DeFi token that preferred. The majority of crypto user preferred Bitcoin as there main coin in there portfolio and most of the investors diversify there investment. If many new traders will surge to buy DeFi token, I'm pretty sure that they will buy BTC too to add on there portfolio.
BTC is just like Gold in precious metal. If a trader will buy silver, they will buy too Gold once they have enough money because human is always looking for more much better things.
