if you want to know simple predictions for the price and future of bitcoin then bitcoin in the future can be very expensive because bitcoin has a very limited total supply and has a very high request so that it can make bitcoin prices very expensive in the future.
Bitcoin is actually fixed in supply so its better than scarce it sort of equals a better gold across the board.I think regardless of the price moves in the last few weeks, its still a very underappreciated asset.
Yeah it is hard because price of bitcoin never remains the same, sometimes price of bitcoin gets bigger because people take interest and they get more investment to save for long time so for me it is not hard to predict the price as this years people are taking more interest as compare to last year according to me 2018 is gonna end as an year of bitcoin.
