I think in the future Bitcoin will be accepted by world governments because Bitcoin is more and more popular on international bulletin boards and many people will know about Bitcoin. I see people in my country moving to Bitcoin more and it is a good signal to invest in Bitcoin right now.
It will be accepted by many governments, but not from all that is what I think, some countries will always try to separate from others. Bitcoin is really accepted now more then ever before, but due high price people are getting interested in other altcoins. I follow altcoin section a lot, and I noticed that some coins have very devoted community behind them, cause of all this I think that some alts also have nice future behind bitcoin, as bitcoin grow some alts will grow as well.
