Personally for me, I spent my Bitcoin for online shopping and games. For example, I bought a Samsung Tablet from Amazon.com last year around this time with the Bitcoin I earned from signature campaign. To add on, I also purchase some fun games with my Bitcoin such as Just Cause 2 and Ark.
So far I'd say I have spend more than a hundred worth of Bitcoin online - not really accurate because Bitcoin price keep changing.
Great, but still very limited way to spend our money online. I like to shop but amazon give me a headache with the shipping fee, maybe you are from Western country that's why you enjoy shopping, but in our country the shipping is really high that you cannot appreciate the price of an item even if it's on sale. My way to spend my bitcoins is only but topping up my mobile load and spending it in gambling regularly.
