If you are currently observing Bitcoin prices, then you will be amazed by the rapid rise and fall of Bitcoin prices (fluctuations). In fact you may also wonder whether companies (such as Luno) that determine the price of Bitcoin? The answer is no, because Bitcoin is interoperable.
Why Bitcoin Prices Are Highly Fluctuating? actually the reason why Bitcoin prices are more volatile than other currencies is; the absence of any entity that controls the price of Bitcoin.
Bitcoin prices are determined by everyone who has Bitcoin (regardless of amount).
If you have Bitcoin right now, you're one of those people who determines the Bitcoin price. If you suddenly sell all your Bitcoin, then the price will move down (because supply / supply is now increased). So also if you suddenly want to buy a lot of Bitcoin, you have contributed to the amount of demand (demand) Bitcoin, so the price will move up.
Now, imagine there are millions of people who have Bitcoin in the world with different selling prices and prices. By collecting them all, you will get the middle value of the market between the demand price and the offer price - and that is the Bitcoin price at that time.
having bitcoin does not mean you can play the price, the price is played by traders who have bitcoins. If we just keep the bitcoin in the wallet it will not affect the rise and fall of the price at all. Therefore many traders are very interested in bitcoin because they understand what kind of price is played.
