There are a lot of factors influencing the price of bitcoin, including technical issues/new alts coming out/regulations/stubborn miners/conflicts between developers(or groups)...etc.
What do you think is the most crucial cause? Why did the price drop dramatically these days? Will this be a rebound point?
Factors that affect the bitcoin are the investors.
I think some investors did not trust the crypto and decided to withdraw their capital. That has made the crypto market in crisis. Bitcoin has gone down at the lowest price of $ 6k5. In addition, I think the stock market has a lot of impact on bitcoins. Top technology companies like Amazon, Alibaba have lost more than $ 100 billion.
