All this means that we have not reached the bottom of 2018 
Do you mean levels below $ 5500 ?, It is not expected to happen.Of course it wasn't expected, but now we are very close to it. I thought it would happen earlier, because this price is not the bottom.
And if I say that bitcoin will cost less than $ 5,000, then again nobody will believe me.
I think on some exchange the price hits $5500 already so we have hit another bottom for the last 52 weeks. But this is not due to the ETF decision though and since we're just like a 'collateral damage' for the Bitcoin Cash war I think its hard to see if this bottom will gonna hold or another series of sell-off will occur post Bitcoin Cash fork. Or if we're going to see $4000-$5000 or worst if SEC rejects the Van Eck/Solid X proposal.
