We haven't moved beyond 21k with this news. It's "that" important, great for Polish people who want to use binance, but that's literally as small of a niche as you can find for a good news. How many Polish people who didn't have a method of buying bitcoin, that ended up having a method of buying bitcoin thanks to Binance being available to them? Not many people, not a lot of money to begin with, hence why the price doesn't move.
I have to say that people are overreacting to the smallest good or bad news based on the momentum, if it's going up, the smallest things look like they could be huge, and when it's bad, then smallest bad things could look like the worst thing ever.
