The volatility of bitcoin is primarily due to the fact that its price is not regulated as ordinary money. In every country, the central bank monitors the stable rate of national money, throwing out additional bills on the market or withdrawing them from circulation. And the rate of national money is strengthened by buying or selling foreign currencies. Bitcoin, on the other hand, no one regulates it. Its rate is determined only by the ratio of supply and demand, and these parameters are very variable. It will be very interesting when the cost of bitcoin reaches high price values and the degree of volatility then increases, the amplitude of fluctuations will be such that the owners of bitcoin will not be able to withstand such a spectacle and the nervous will sell it.
