buying pizza
DUDE!!! PIZZA!!
In my country there are a lot of places to spend your coins just like fiat! shops, bars, restaurants. If you miss it in your area, try to set it up yourself, find people nearby to set up a monthly meeting, brainstorm about how you could get local merchant to join in on the bitcoin!
In my country.. Only a few shops accept Bitcoin. I know many people in my country use Bitcoin.. But not many shops owner are willing to accept Bitcoin.
Other than Black market.. many people now use Bitcoin to buy online games. Such as Minecraft and Battlefield 3/4. I personally use Bitcoin to buy things from Amazon.
