Eventually the credit card companies will come around...just like they did when it was decided that paper checks were an insufficient means of remitting payments...they will see the advantage of providing cards for cryptocurrencies and jump on board...otherwise somebody will get in on the ground floor before them and they don't want to lose out on all that money...it's going to take time because the ruling elite are not going to give up their lofty positions of greed voluntarily...they will continue to grasp at anything they can to ensure their own survival...
