I know bitcoin when it price 300$. But i don't buy Bitcoin cause i can't believe it. Today btc price highly increase but why? Can you tell what reason?
The law of demand and supply is the general reason. Bitcoin adoption of companies and rich personalities had huge impact on the current price of bitcoin today. There's also lots of bitcoin holders nowadays, meaning many bitcoins have been put on hold, it does affects the price of bitcoin since there's less circulating supply that is willing to be sold in lthe market.
