Centralized electronic payment processors such as Visa, Mastercard and co raising their fees is the least of the problems, the big problem would be the loss of financial privacy.
Bitcoin would obviously pump massively at the news of relevant countries going cashless. However the rise of demand for block space would raise Bitcoin fees as well, so second layer solutions must be ready by then to profit from the perfect storm.
Privacy is a big yhing. Paying for anything in cash means the transaction
is untraceable. Cash is on the way out, in my country it is difficult to pay
utilities like, electricity, phone, internet, waste collection, t.v. payment is widely
accepted or preferred by card or through the bank.
I would imagine card transaction fees would rise but not by 2000%, that is
just unsustainable. At the moment with "tap and go" card payments i can
buy a bottle of water for €1 and pay with card and walk away within 20
seconds, high fees for these payments wont work.
There really is no competition, in Europe its either Visa or Mastercard, not
a great start for competition.
