I do not believe that the price of bitcoin can go out of control. There are people who have a lot of coins. They can't release control over the pricing of their hands. As a result, they can lose a lot of money. It seems to me that they turned the pump on purpose. Perhaps speculators are afraid of futures and preparing to leave the market of bitcoin.
Bitcoin is decentralized one,so no one can control the price of bitcoin.The price of bitcoin is 16,153$,it crossed the 16.1k$.It just an miracle to see this price.Many holders had a very good news and will get their christmas gift for the bitcoin.No one will allow to bitcoin to end,many had inverse their money in bitcoin.
bitcoin cant be contolled but it can still be maipulated by whales or the people who had much power to buy or sell boat loads of it and this thus totally affect the balance of supply and demand to hit directly the market of bitcoin. the price of bitcoin is still soaring high because many new individuals day by day are going for bitcoin to think that they can still catch up on this hype and make a descent amount of profit soon if bitcoin continues to surge dramatically. bitcoin is decentralized but some countries now are planning to make it centralized so that they can fully control and manage it to be able to make their own law and rules like putting a certain amount of tax to the the user of bitcoin.
