I spend a fair bit of BTC. I tend to use it to buy items that'll improve my life. That way I won't be sad if the price ever reaches squillions of dollars as I got plenty of good use from whatever I bought.

Unless I had no alternative, and I do, I wouldn't spend it on consumables like food, coffee, fuel. That stuff eventually comes out of my arse, urethra or exhaust pipe never to be seen again, though it was certainly useful at the time.

The key to spending is earning in BTC. And those who bought for a lot less have earned more buying power in a sense too. If you've got it coming in then you'll be more inclined to spend it. If you've laid out your dollars in the hope of doing well, and are yet to, and underwent all that hassle to obtain it then you'll be far less willing to spend. You'll want to hoard.

A lot of attitudes and circumstances will need to change for it to see regular use as a currency. We're nowhere near it now. We may never be.
