No one can predict this of course but to be honest I think it will be around the 800 dollar most likely.
Another nice fact would be if it is stable on that price right ?
Yes this will be a very nice fact mainly because it would be better for people to use as money (buy and sell).
Bitcoin is going to be more worth later but it wont be that high because there are still a lot of people that is holding there Bitcoin for a nice value so they can have a huge profit.
You are only not for sure that it is going to rise but we are hoping it because it was already stable for a long time.
