Bitcoin is controlled by people like you and me who believe in Bitcoin and want to collect Bitcoin. If we all start selling Bitcoin then it will definitely go down in price. And if we continue to buy Bitcoin without selling it, its price will definitely go up. And it always happens that everything depends on people like us.There is no miracle behind it he he
Bitcoin price does move based on supply and demand, so as you said the price of Bitcoin will increase if more people buy it. Then the price of
Bitcoin will decrease even more if more people sell it. So the price of Bitcoin moves naturally according to what is happening in the market,
therefore the price of Bitcoin is very volatile and difficult to predict. The volatile Bitcoin price allows Bitcoin to be used as an asset, different from
fiat whose prices are stable. That's why the popularity of Bitcoin is increasing, because storing Bitcoin is much more profitable than storing fiat.
The conclusion is very difficult if individuals or groups control the price of Bitcoin, because the Bitcoin market is already so large, so need a large
amount of Bitcoin if anyone wants to control the price of Bitcoin.
