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.
The more popular Bitcoin will become, the more problems holders will have! Government and traditional banks don't want to share their profit or authority with anyone. If one coin can replace traditional money system is's very disturbing signal.
