Re: Hey guys, I've finally found the antichrist!!
If it were secure, maybe, but bitcoin has been hacked twice now, with hundreds of $millions in value stolen to date, and the losses spread across all the account holders. No, I don't see it becoming a universally adopted means of exchange for every trxn, not even in 50 years time. For a start, the elites controlling the banking system will never allow it.
They have almost limitless resources to sabotage it, and it wouldn't surprise me if they were behind the hacks. As a 'conspiracy', that's infintely more plausible than your scenario of 'the antichrist's currency'. Revelation explicitly tells us that the number 666 is the number of a man, not an exchange rate against a currency, which constantly fluctuates anyway, and is currently a little under $900.
But since you're only looking for a little conspiracy fun, I have to assume your tongue was firmly planted in your cheek while you were posting.
