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.
Who knows? Well, maybe by the end of 2019 it will be much higher than $10K although it's too early to predict because 2018 is yet to end. For the mean time let us just hope for bitcoin to have a good market by the end of the year for a more profitable earnings.
