There won't be any war against bitcoin in the future because that war started years ago and has been raging on ever since.
I agree, since the release of bitcoin's whitepaper, seeds of doubts are planted by many people and are still skeptic till this day. Also, OP seems a bit edgy with his talk of war against cryptocurrency, "war" seems like a big word for whatever is happening right now, although I can't find the one that fits it, I think that the word "war" is a bit strong.
