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,?
Just don't panic to sell if the price goes down because that is normal in trading. Selling if the price is low is not a good idea however you need to do is just hold until the price rises up again. Bitcoin is too big to lose so you can never go wrong if you will either buy or hold.
