Bitcoin price is controllable by the big whales. While bit coin is uncontrollable by the whales. Bitcoin system can corntrol actually by those investors who own much numbers of bitcoin. For me this system is like controllable but uncontrollable in reality. Like the limit numbers of supply, limitations of bitcoin in the physical world of system. Bitcoin system can own by one person, can manipulate by one person. Although bitcoin is unpredictable in terms of price that system is clear.
