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?
Defenitely media cause more damages than any other factor with cryotocurrency prices because media is everywhere if there is little negative thing about bitcoin will go viral in short period of time and do enough damages before knowing the real reason behind it,mostly there are rumors more than the real news.
