Why dont you want to sell your coins i dont think there are so many people who want to selltheir coins right now because the price of the bitcoin is not very high at the moment.
If the past bitcoin price performance is of any guidance, the price of the bitcoin will rise a lot in the future.
Price will definitely rise in future but when we see higher price we should sell some of them in order to make profits from it and we can buy it again when price drops in future.
