You should just not sell your bitcoins because the price will go to a much higher point soon or later.
I even think there is a chance by just using the bitcoin as a investment and in a long term you can get really rich.
Yeah I hope what you are saying can be true in future, investing in bitcoins is little risky as no is sure about its future, but I think we should take that risk and invest in it at a moment.
Investing money in bitcoin is surely very risky affair as we never know where bitcoin will stand in future, but having some bitcoins in wallet for future would be good investment to make I guess.
