Hello!
How BTC's price change? What are the factors that affect the rise and fall of the BTC?
The good ones that affect the increase or decrease in bitcoin for me are:
1. Depend on the market economy.
2. The psychology of bitcoin users if there is fraud.
3. The bitcoin market is in the United States, China, Japan. Places where many people invest in bitcoin.
Better to analyze market data to understnad what drives markets. Supply is limited for bitcoin and demand grows daily. Prices react to this daily demand level with falling/rising during given timeframe.
