There's a currency war coming and VISA can either win or lose, right?
In the long run, cryptocurrencies might become a threat to VISA. But for now, VISA is a titan with a tick in the back.
Until now people could buy cryptocurrencies using VISA, but they decided to stop processing any transaction related to crypto.
Why? Well one could argue that VISA was making (a lot of) money with bitcoin purchases, so they should keep profiting from it. I agree with that, but only IF they were thinking about moving their business to the crypto world. But it's not the case and while they were profiting on fiat, they were feeding crypto, which, instead of generating fees and interest, it values in time.
Can you imagine what will happen once everybody understands this simple fact?
This shows how desperate they are, and how powerful cryptocurrencies are.
VISA, the titan, is scared. Next time you think about selling your crypto, remember VISA isn't sleeping anymore because you bought crypto :)
