Well, I think the best thing to do right now is just to hold all your coins. It involves absolutely no risk at all and it's definietly going to be very profitable indeed with the current halving coming up.
Sell it when the halving comes. I bet there will be a market adjustment, and you can get more coins!!!
Holding now is really a brave thing to do. I have sold mine seeing the really big leap of bitcoin price. I thought it will never grew again. But still I am in profit if I buy some for a lower price. If it will still fall back
