Everybody needs to also stop using Mastercard/Visa/Paypal.

Is there any good reason why shops/Vendors dont really offer any kind of Crypto? Like I genuinely dont get it aren’t you paying way more for using Visa/Mastercard etc. as a shop?

Because crypto isn’t really a currency as much as it is a volatile asset. Businesses require stability to run coherently, and utilizing something like crypto currency which could massively increase or decrease in value following a breaking news report isn’t something that large organizations can really tolerate.
