Yeah, it is the volatility nature of Bitcoin that made it rise massively to $23K some few months ago. This is a good property of Bitcoin as it makes the market demand goes up and create more market niche for the crypto world. Let's appreciate the good side of the volatility nature for once.
It is very simple to explain.Bitcoin's price depends on the forces of demand and supply.If the demand is high then the prices will definitely rise.On the other hand if the supply is more then prices will fall down.Prices also depend on how much people invest in bitcoin.If more people invest in it then for sure its price will rise or otheriwse vice versa will happen if investment is less.Another reason is if people hold or release their bitcoins in the market.Bitcoin has a very huge market too compared to any other cryptocurrency.
