Well what I know is that we can't predict the future though many have already taken a wild guess. Whether bitcoin will survive the future or not is the answer is can't give currently but what I know is that the technology behind it which is blockchain will keep evolving. Bitcoin is just a currency on top of blockchain but the technology use us what marvels me. Based on the current hype surrounding it, I think blockchain will evolve and keep evolving in the future. Government will try but won't succeed.
Even if we cannot predict the future, I am certain of one thing; it all balls down to the community as a whole. The government may have some say with regulations but that would be all it is to the whole thing. Bitcoin is not just a currency, it is a legacy and one that has been used hugely and being adopted gradually for large scale.
A lot of people are already seeing the value decentralization brings, and even though during the G20 summit, it was not classified as a threat, but I am sure it is a big one as people start realizing how shitty the fiat system is. That day is not far away as per we are seeing how fast cryptocurrencies are getting familiar among common people.
Bitcoin will not disappear for sure unless otherwise this planet is safe against natural calamities and biological/atomic weapons. If you think that I am kidding then we must say at least internet and power supply must stay alive so that we can keep bitcoin to stay with us all the times.
