Just to be the one to point this out. I firmly believe that Crypto-currencies will be adopted by Government (If they weren't really invented by one to begin with) and will be tied to microchip implants. This is exactly what the Bible foretold 2000 plus years ago would happen. If I am wrong, no big deal, just some crazy Christian right? But if and when you begin to see microchipping of humans (Oh yeah they already are...) then you might want to pause and think. I could point out that RFID microchips can be equated with the number 666 as well. If A=1 B=2 Etc....Then R=18 and 3x3x2=18....F=6 and 2x3=6....I=9 and 3x3=9....D=4 and only 2x2=4. If you take the common denominator of the first three letters, 3, and multiply it by the common denominator of the last letter, 2, then you get 2x3, 2x3, 2x3 or 666. Just something to think about....
