Do you think crypto is not a visionary thing? while Visa is a large company that accepts Crypto as their new line of business and is currently expanding to other institutional networks. Isn't this service able to increase the market more broadly?
It's the same thing as Mastercard wants, they want banks to offer crypto products while both Visa and Mastercard to be used as a link between crypto and fiat, they don't plan on adopting bitcoin, they don't plan on using any crypto on their infrastructure they just want banks to accept crypto which will be converted to fiat and used on traditional cards. That's it, nothing "revolutionary", just their way as a business to try and milk some more profits of a new sector, neither "visionary". Besides we had Visa offering its cards for banks and businesses that want to deal with crypto for a long time, counted in years. Visa is a business, it's normal for them to explore a way of making more money.
The revolution will only happen once they will allow crypto settlement on their chain, and unfortunately, there is not a single squeak about something like that. But what would be the point of that really, deposit your coins to a bank, use a centralized solution for payments, basically adding not the just but two intermediaries when Bitcoin was supposed to get rid of them?
