Digital currencies are definitely the future of the finance now. There is no way out of this so some people who are antagonists to Bitcoin and the rest of the cryptocurrencies should stop their attitude for their own benefit. In the future, we won't have any fiat currency left. In this kind of a world, people will have no choice other than using digital currencies. It is better to make an effort to get used to them already now.
Yes but the OP referred to a potential new world order, hence who is in control over the currency that the people are using? Is it a decentralized network like Bitcoin and will it stay decentralized for its most part? Or will it be a digital currency forced up onto the citizens around the world? Those are two very different scenarios with different consequences for everyone. No matter what is going to happen, but it is important to have decentralized systems like Bitcoin, Ethereum etc. just to have some counterpart to any Central Bank Digital Currency that might get established. Nobody can really know how it pans out exactly over the next ten or so years, but a ban of cryptocurrencies passed by old politicians would be a mistake and shortsighted.
I would suggest that if we ever have "new world order" which I believe won't happen, then it is likely that something like a decentralized cryptocurrency would be at the top of it. I understand that not everyone falls in love with that idea right now and governments will try their best to not get that happen and will use all of their police power to sotp it if it comes to that.
However, if we are talking about new world order then people at the top (there is always some people at the top) may look at crypto in a different light. That is why I believe that crypto could be the currency of the future, or maybe none of that will happen and crypto will just become a popular alternative to payment methods we have right now.
Like we do pay with cash, or we pay with card, that is 95%+ of all payments in the world when you go to a place, or we wire transfer money to other people if it is not in person payments, all of that could be replaced with crypto, so it will be a good alternative in the future.
