In 10 years? 90% to be ~$0-100. 10% to rise to ~$150k. Most likely countries like USA will punish people using BTC and it will be pretty much worthless.
USA has the most Bitcoin users in this world so I think that will not happen, and even if bitcoin was banned to this country, they will be finding ways to sell or buy bitcoin to be saved and use in other way that they will not be punished. What I hope in that 10 years is the development of bitcoin that it will not be having any problem like what is the issue today.
Of course USA have the most people that adopting bitcoin but it does not mean that if they gone, there will be nothing left on bitcoin. I will say no matter what, they will always find way to get those coin or if they want to dump it, people from others country will still take it for sure, no one want to let bitcoin price fall for sure. It is like catching some rain. So I believe bitcoin economy in the 10 years later will be better
