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.
We are not sure if if really brings a lot of institutional money to bitcoin market if ever a likelihood of ETF's being approved and implemented. The worst thing that will happen its that Bitcoin will formed another bubble and then suddenly pops up causing the price to crash again. So I still have mix emotions, but just like others say have, let's see how it pan outs. But just be ready when all the hype died down bringing the price to its knees again.
