We are not talking about crypto currencies. We are talking about visa and MasterCard which use a centralized network to process those payments. That is as cheap as it can get. The power requirements for crypto currencies are the main reason I oppose them. They are a great idea but useless because mining and verifying transactions puts such a strain on our environment that I couldn’t justify the advantages for everyday use. And a crypto currency with doesn’t require a lot of power kind of misses the point.
