Nah, I just hold them. The price is too low at the moment. If I sell them now or use them to buy stuff, I guess I would be off at a loss. But I'm looking forward to use my BTC to buy something in the future when the price goes back up again! Maybe even into a new bubble!
Why wouldn't you spend your BTC, then buy an equal amount of BTC on an exchange and/or on a trade? This would increase the amount of BTC adoption, will likely allow you to buy goods at a discount and increase the size of the bitcoin economy.
