Stock trades went to $0 long ago, yet crypto exchanges continue to charge around 0.5% (with some discounts if you're savvy) and nobody bats an eye.
But then again, I can send money anywhere for basically $0, yet everything I do with cryptocurrency comes with transaction fees and waits. I wonder if crypto users are basically more primed to expect fees and crypto exchanges are better at making users forget about it with clever UX?
Either way, I expect exchange profits will decline slowly as they begin competing with each other more.
