I think its 50/50 benefitted in both sides. However, with or without DeFi Bitcoin will remain as the largest cryptocurrency in the market. The trend and popularity will continuously spreading all around the world as many people are trusting it, unlike DeFi which has a new existence to people and I absolutely have doubts with their projects.
not 50/50 because btc is more larger than defi and btc is more supreme than defi . it can be 50/25 , 50 percent is what btc being contributed to defi and 25 percent is what defi brings to btc .
theres only one btc and its easy to follow it if it will do good or not . btc did because its been here for a long time but for defi there isnt only one defi projects created but theres hundreds of them so far , time will come and they will reach thousands or more . this makes them hard to follow and judge
