Hii.. are you need money for some needed near this time? If you need it you can sell your BTC and use it for your needed. If you don't have needed or something urgent near this time, I suggest you to hold it until your losses recovery back.
Because pur main purpose when invest is to get the profit, if we don't get the profit why we sell it? that's so bad idea, except you have something urgent which that should use your BTC.
