People here are right about the reversal because if a movement is starting in bitcoin it sure goes a long time before it stops, however don't think just because it dropped couple bucks its a reversal, its not, you should wait at least 100 dollars before you decide on moving forward with the strategy.

Hence, if you see bitcoin going from 7.2 thousand dollar levels to 7 thousand dollars levels than you can be certain that it will go even further down and not stay there, if you see bitcoin going from 6.4 thousand dollar levels to 6.6 thousand dollar levels you can be certain its going further as well.
