They can try as much as they want to stall the upcoming surge of the everyday usage of bitcoin but they can't run away too far. In the end no matter what happens there will be a time when bitcoin exchanges or wallets or banks or whatever you want to call it will have a system like mobile payment app or sorts and we will see a lot of new stuff for payment as well which would allow people to do all of this without the worry of visa or mastercard doing whatever they want to.
The only thing required is one crypto company and one bank agreeing on working globally on a mobile app that would allow people to do this, that's it. One agreement, one deal, one contract. As soon as that happens we are off to the races.
They obviously cannot run away for so long and they would have to come around one way or the other. At least there was a time they never really wanted anything to do with cryptocurrency as a whole and then now, we are seeing them tightening requirements for the issuers. It is a start, we sure know development will not just come up overnight and it is a gradual process.
However they want to play their cards now is best known to them, but we certainly know this is a growing space, and one way or the other it would boom more than this in the long run. They can decide to take it or leave it.
