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?
Definitely this is because of the black propaganda against bitcoins and any other cryptocurriencies. Investors who are weak got scared off and withdraw their investments also this could be cause with the banning of cryptocurrencies in some countries in the world. The bitcoin market has been shaken up quite well but the good news is it is fighting back and has shown improvements in price in the past days👍
