You do not have to be pessimistic or be afraid with this fall that bitcoin suffers, I read that by 2019 the price of bitcoin will reach 10K for this reason you have to be patient and not panic.
It is really difficult to predict when the price will recover but everyone in this market knows that the price will recover, it may take a couple of years to recover or it might recover by the end of this year, what ever it may be one thing is sure is that investing in this market will give you the best profit rather than investing in any other market.
