All this means that we have not reached the bottom of 2018 
Do you mean levels below $ 5500 ?, It is not expected to happen.About three weeks ago, "before the news about Khalid," the price was around $ 6,200, after which the price plummeted to $ 8000 due to optimism and then returned to the same levels after the postponement decision.
So it will be repeated until the decision to reject or accept "which leads to a rise above $ 8000 or fall below $ 6000" in the short-term only.
In the long-term: the price will recover and start to rise again to over $ 10,000, especially if the lightning network is activated but the real question is when?
ETF or others are the reasons that lead to increases in the short-term only.
If you're afraid of the price, the real trader knows how to gain from both falling and rising "you could earn $ 2000 from last week."
You are too fixated about the price. The ETF is just one of the factors influencing the price. I agree that if an ETF is approved, it could result in a lot of money flowing into Bitcoin. But you have multiple other factors, including debates within the bitcoin community, whales selling, Trump unsettling global markets, etc.
