Simply because the WHALES take the profits whenever there's a 5 to 10 percent growth. The bottom line is Swing trading and Day trading is real and the HODL method is just what it is...
I agree with your words mate the whales always playing the price of bitcoin to their hands and they will not stop until they have filled their pockets. Good thing to do is use this opportunity to buy a bitcoin at a cheap price then hold, it might be before year end the bitcoin price will pump again.
