Nobody knows credit card transactions and how they work more than Visa. I find it highly unlikely that they didn’t know that re-charging people and refunding the original charge would cause huge problems for consumers.
Most of us have probably returned goods that we purchased on a credit card. We all know it takes several days for the refund to appear, it is never instant or the same day. Pretty much everybody who has used a credit card knows this simple fact. Yet, we are to believe that Visa didn’t know that re-charging people and refunding the original charge would cause people to have extra funds unavailable in their account?
Likely. There's also the news that certain central banks actually paid out YouTubers and had them demean and insult cryptocurrencies. Looks like the dinosaurs are getting scared.
