I'd still say far more people are holding it as an investment commodity at the moment than actually spending it. People can see the long term potential in it so they are reluctant to spend it but likely will in the future when adoption is more widespread.
They're probably spending it now they're bored of it as an investment. I'm sure there are a few hard core users who only utilise it for spending. The majority got some in the hope of it rising.
It needs to become some type of store of value before it can become anything like a mainstream currency. Spending and replacing helps that along.
