it is not possible for all markets just go up or down.
Bitcoin ups to 20k not go downs as it is needed. Otherwise, we cant talk a healthy market growth.
So dont let your mood go down with this movement.
it is obious that all speculators from conventional markets are playing in crypto markets. they know how to speculate and here there is not any rule!!!
they can do everything they want and they are doing.
please just keep calm and wait some while.
I believe that Bitcoin will se 30.000 USD in 2018 not less...
Keep calm, keep trust!!!
