What if somebody will make a huge dump and sell it all the way to earn some profits because of this rally in bitcoin,and someone sees it and do that same thing. Is there any effect on bitcoin when someone to this,?
Yes there's effect maybe some of hoders sell threir bitcoin and some make a panic selling. But i think some are holding their bitcoin because they know once bitcoin down the price thet will pump it again.
Smart people will take advantage of that situation by buying more coins and holding their existing coins without selling them as they very well know that if price has gone down it will surely rise once again in future.
