It really depends on the price of Bitcoin at the time. If the price of Bitcoin is high, I would sell, but when it's low i would buy. You could make money with Bitcoin this way. Trading is a great was many people make money with Bitcoin.
sometimes I was very pleased when buying bitcoin at low prices and then prices go up some time. it is the best moment to buy goods. because you can get the goods with fewer number of bitcoin.
so I usually spend bitcoin when the price is high
