Nitrogen sports will pay you for your nitrogen tattoo. First 10 people will get 0.1 BTC for tattoo, and the best tattoo selected from nitrogen stuff will get 0.3 BTC more, sounds crazy right?
I didn't know where to post this, but this is about earning money and marketplace is the best place for that.

One guy already did it and post his work on youtube, take a look.

This is funny for me, I don't have tattoos and I don't think about making one now, what is about you? Who would do this from here for 1000 dollars? If you wish to do it hurry up just 9 more spots left.
