Probably because the big payment processors, VISA & MasterCard dont like Payoneer and if a company makes any electronic transactions outside of Russia & China they will be working with them. So if they hint heavily at a company they might want to think about their support for Payoneer, they don't have much choice but to drop them.
And crypto wont win, the cryptocoins & cryptocurrency exchanges banks & payment processors will accept & do business with shrinks daily. And crypto exchanges imploding regularly really doesnt help matters.
