I don't think ETF don't affect the price of bitcoins because all i see is a big drop of bitcoins price on rejection of ETF but in any way bitcoins will go again and continue soon to rise with or without ETF . So you do trade and it is good as of now because most of the altcoins are being pump for the mean time . So both is good as we hold some BTC to wait and some amount to invest in trade.
After the decision that ETH was disapproved was announced, there was no sudden big drop in the price of bitcoin. What caused this huge drop in the bitcoin price is the Bitcoin unlimited thing, AKA the hard fork drama. But right now, we're starting to get back on track because there's no actual market for the BCU tokens at all. The whole thing was just created by FUD, panic sellers, wannabe early investors and so on.
Now the price of BCU is starting to go down, because you know. Not everyone's interested at all. I pity those people that announced how many thousand dollars they invested for BCU.
