Really? You had to read an article to go "well damn, I guess haven't bought anything with bitcoin"? Really? 

You have the right to see it as whatever you want. To you, it's an investment, to others, it's an asset with a 'store of value' property, to me, it's all of that plus something that works as a medium of exchange.

I've lost count of the things I've bought with BTC over the years: from domains, seedboxes, to t-shirts, few cups of coffee, hard drives, etc.
