"Total global economic collapse and the introduction of a new world digital currency...."

Some people who are afraid of the New World Order have often accused Bitcoin for being the New World Digital Currency and thus Bitcoin is believed to be evil. It's weird to think that Bitcoin could actually be an important piece of the Illuminati's plan.

So, let's say Bitcoin and the block chain technology were never invented. What would be the new world digital currency then? Could it be the debit/credit card system? Apple pay? Just to try and take the position of a devil's advocate in this situation, is there any realistic possibility of how Bitcoin could turn out to be the new world digital currency that the referred video is talking about?
