Bitcoin’s price is falling because demand for Bitcoin is lower than the supply of Bitcoin. The law of supply and demand says that when there is more of something than people want to buy, the price goes down.
The reason demand for Bitcoin is lower than its supply could be because:
1) Fewer people are using Bitcoin to buy goods and services. This could be because people are losing faith in Bitcoin, or because they are using other cryptocurrencies instead.
2) More people are selling Bitcoin than buying it. This could be because they need the money, or because they think the price will continue to fall.
3) Miners are selling more Bitcoin than they are keeping as a reserve. This could be because they need the money to pay their costs, or because they think the price will continue to fall.
Whatever the reason, the result is the same: the price of Bitcoin is falling because there is more Bitcoin available than people want to buy it.
