The market recently has matured and such news doesn't change anything. In fact, more traders realize that such news trigger short lived bull balloons that pop up pretty quickly. Without ETF, we will see a steady growth beyond 20K. We entered the year-before-the-halving-accumulation zone and everyone who is clever enough, buys and waits at least six months after the halving. That is the reason there are so few bitcoins on the exchanges in the last months. IMO, this is the main reason for the bull run and not some rumors.
In this case you can buy now and hold till Q4 then sell at $20k+ (I'm sure we'll see an ATH this year) which will be a very nice profit. If you're patient enough you can hold up to 6 months after the halving and sell at another ATH ($100-500k+ per BTC). So you can't really lose it's only a matter of how long you're willing to wait and how much money you will finally receive. Win-win
