I believe this fall of price is great opportunity to buy..just like when the hacking of Binance exchange happened..the price fall 30 % then recovered and went up 40 %..
Even this thing with closing general Binance exchange for Americans and founding separate US Binance will be good at the end... and the price will recover to 0.0040 - 0.0050 range. we just have to be patient. I started buying from  and 0.0039 btc and still buying as the price goes down....
