Nevertheless, I want to know your opinion about this, since it would be pretty cool to have such a system to help spread mass adoption of the cryptocurrency. 
No, it wouldn't. Sounds a lot like Revelation, referring to the Anti-Christ's mark.
"And he causes all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: and that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name"
If any man worship the beast and his image, and receive his mark the same shall drink of the wine of the wrath of God
Thanks. I've been waiting for some christian fear monger to post that.
Abit of topic but how is he a fearmonger for quoting the bible? He didn't even interpret anything ? i hate when people just brand someone with a label instead of debating the point
Ok, I'll debate it. Why bring up that passage at all? Most of the christian bible is designed to instill fear. The bible doesn't say things like, "don't do that because god will be really disappointed and pout if you do". No, the bible says things like, "don't do that or god will allow you to go to a fiery hell and be tortured for all eternity". WTF?
This forum is called "Bitcointalk" not "Christians intrepret money". It's a financial website discussing a revolutionary monetary tool. Keep that christian fear-mongering shit in the circus where it belongs.
