In fact, the biblical interpretation of 666, as you describe it there, refers to political power throughout the ages, which has always exerted its influence like a ‘wild beast’ that devours and destroys societies with the claws of corruption, abuse of power, influence peddling and mismanagement. It has always been this way, from ancient Rome to the pseudo-democratic governments of today. As Lord Acton would say: "Power corrupts, but absolute power corrupts absolutely."
But the fact that that number appears in your wallet is nothing more than a mere numerical coincidence. 😅
