Yes, there can be a big war coming but nobody knows for sure if that can happen because banking can also adopt with the cryptocurrency platform anytime they want to. Compare to the volume of transactions handled by the baking sector, Bitcoin is just a small peanut (though of course it can disrupt this market). It is not yet time to have this war as Bitcoin is now also having its own internal war happening. It is a small shame to be shouting to the whole world that we are the best but we could not contain the bickering in our own backyard.
