Just wow. Visa doing duplicate transactions is a big blunder on them cause if someone did a $10,000 buy on their credit card from coinbase then they would of received a double charge costing them $20,000 and probably causing their card to go over the limit then charging them a fee going over that hard limit.
Sheesh what a mess.
Yep that's crazy, it can make innocent people to get into a real panic mode.
I am glad to see that it wasn't coinbase double charging but it was visa, I just can't understand how a big organization such visa can have this flew, don't they have people who checks the system,double-charge is not a very hard thing to determine.
I guess that even big companies can have novices mistakes.
