There is no benefit of selling your btc now, you will face huge lose if you have bought it at high price. And its not like that the price will not increase, the price will increase in some more time. So will for some more time, you will definitely get good profit through btc.
I don't think its a good idea to sell your bitcoin now that the price is too low, you will loose your investment on it. If you really need to sell, just sell some part of it and not all, atleast you still have bitcoin if the price goes up.
