It is interesting that I did no see in the comments the costs of using Mastercard & Visa as a reason for governments to find alternatives for their economies.

Both Visa and MC are US companies so there is where the profits go ....

From US Senate hearing : "This is classic, classic monopolistic behavior. Yet you're testimony...is you don't want any competition...I'm having a hard time finding that position defensible, let alone sympathetic...it's unbelievable the amount of money you're making."

Margin 50% ....

I think more than cost; it is more a desire for sovereignty and also making everything trackable. As happened in Russia, US govt can block Mastercard/Visa from the country or can block a company like Huawei and local govt has no say in it.
