Yes those big people or should I say people that has big amount of bitcoins are the ones that are capable of manipulating the bitcoins price. And right now, we are seeing on how they are manipulating the price of bitcoin and too bad for us who are just small holders we are just going along with the flow of these whales.
Not only big whales or miners could manipulate the price of bitcoin but also the power of the masses. If a big number of bitcoin holders started to panic and dumped their bitcoins the price will suddenly dropped but if they were convinced that bitcoin is good to go the price will inflate no matter what. At this point of time the power of the masses in the bitcoin community is much stronger than the whales. The whales have dumped bitcoin man times but the large number of bitcoin supporters saw this as an opportunity to get hold of bitcoins and thus the price deflation has turn into price increase.
