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.
Yeah but there is a big difference in spending and selling I think if you see higher price the you should sell it and convert it to fiat to get more benefits from it.
If there is a big bitcoin price bubble, I will sell and spend the bitcoin. If there is no big bubble, I will just use it.
