Coinbase and other large exchanges wont fall nor take a hit in the least if the ETF fails, I personally think that all this hype due to the prices going so high due to the insane amount of people that are going to want to buy and sell are just an insane amount of bullshit spewed by people who want to make a quick buck off people. The large sell off or buy isn't going to occur, demand will just increase and the price may go up a bit and go down a bit.
All I see is the price coming to some sort of stabilization in some time after the ETF is approved, IF IT IS APPROVED. These exchanges have such a hold on all of the purchases that I just don't think they'd fall even during a high amount of selling and not enough buying to support it.
Etf and coinbase have a lot of difference.
In my mind, btc can up with etf, but etf cant make btc fall
Tough wording but I'll agree with you partly, the ETF won't make BTC fall in the least it just won't happen even if some random dudes on the internet attempted to make people think this.
