Bitcoin 30% drop was not due to corana virus but in correlation with the stock market that has been in a parabolic rise since 2008, corana virus was only the trigger and it can never be the fundamental cause of both stocks and cryptocurrency markets.
After weeks, the stock is still dumping while on the other hand Bitcoin is doing well i guess it has already decoupled from stock after Institutional pulled out and came back seeking safe haven to store their wealth.
