Yes whenever bitcoin price go down its good to buy it and hold for it or stock in tour wallet. Because the value of bitcoin was not stable and it changes every seconds so the only thing that you need to do was to wait unil pump again to get more profit from it. Look on its price right now it was too high I think if we bought bitcoin as early we are all now a millionaire but we dont need to worry because its still guving as a chance so lets grab it and believe in bitcoin that it will continue to increase before this year end.
