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.
10k$ is not the number that investors are headed for. Because in 2017 it reached 20k$. You mean we will wait two years to get 9k$
If a year after the bitcoin value is only in 9k$ , it's actually the truth of bitcoin. Investors expect more in it. And it might lose the number one position in the cryto world
