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.
You got it, even if they do I guess there's no drastic change will be made as people are now enlightened on that fact. Fairly say bulls are not into the arena by now but they are aware in its presence by the time it enters the show will be good to watch.
