If you check the candle chart and note the double tops at 3.5 and then 2.5 respectively it looks likely a bug dump could be on the cards if support at 1.5 is broken.

Considering there has been no major shareholder changes then private investors might be over leveraged and a small dump could trigger a massive dump on margin calls.

Given that there is unlikely to be any significant news soon the shorters may see this as an opportunity to squeeze.
