I refuse to believe that bitcoin with such a huge volume,found across almost a exchange and hold by majority of traders can be manipulated by guys who call themselves whales.
To me I think that it was only possible when the bitcoin price was trading in a low price, where the investors were not too much and it was easy for them to manipulate the bitcoin price, but now we can see that with the increasing number of bitcoin users it is now becoming difficult and harder for the people to manipulate bitcoin price.
