Ya. I mean you want to promote btc and show you're a member of it. Which makes sense. 

But would you get a tattoo of a dollar bill or a peso on your skin? Probably not. 

What you could do is leverage your integration into btc community to show an increased "status" with a fancy car or something. It needs more thought but I think you get the point 

 I would only get a permanent tattoo of a fundamental principle that will never change  

 "christ is king" is the go-to then
