I think ETF didn't effect and influence bitcoin, I don't have seems wrong about ETF. But many people said that ETF gives bitcoin a lot of money if that will be approved by SEC and ETF is an important tool that will largen bitcoin security and privacy.
I think the opposite is true
ETF has a great impact on the market as a whole
But with an important note regarding the bitcoin price
If the ETF agrees chances of rising prices will be great
If an ETF is rejected, go to low prices will be limited.
