we need improvement in the face of this situation.

Yes, you are right in 2018 is indeed a lot of surprises. Last month the price of Bitcoin greatly decreased dramatically but this month seems to have started to improve again. I do not know the next month's Bitcoin prices will continue to grow or vice versa. And the price of Altcoin depends on Bitcoin.
