By and large, women on Bumble don't make the first move. Opening with "Hi" isn't a move, which is what many women on Bumble do to qualify the app's requirement that the woman speaks first.
I've lost track of how many matches I've had on Bumble where they didn't quite get the point of the app, and would open with something like "Impress me". Like, there's a hundred other apps you could use if you don't actually want to make the first move, why use the ONE where you're supposed to if you're not going to do it?
