It is not that simple. Bankers in general are quite greedy. But this is more like an issue which can affect their very survival. With the announcement from El Salvador (making BTC as legal tender), Bitcoin is now being regarded as a competitor to fiat currency). That makes it a competitor to the banking system as well. I am expecting more hostile action from fiat based economies such as the United States, and from the bankers. The honeymoon period for cryptocurrency seems to be over. It should be ready to face tough challenges now.
I've been observing lately many positions and actions like this. The decentralization is the most effective weapon against the old sytem, which doesn't want to loose the control. From now on countries and more countries will try to bring back this control to them using subterfuges promises that accept the digital coins in their business.
Banks know the impact and the power of this crypto financial backing, which is something never well metabolized by them. They'll fight as never before to re-take the control, but the new age currency is like computing and beyond.
The non touchable (software) and the touchable (hardware) were joined to has no limits, and perhaps no control!
