I would hold on to my Bitcoin for sometime. I personally believe that Bitcoin will not stay at the 200 or 300 range in the future.
Predicting for the next 5-10 years is nearly impossible don't you think? Why not hold on to the BTC till the value goes up at the next halving? That is what most of us are waiting for. Think for a shorter term prediction - say the next 1-2 months.
