I think that this will inevitably happen before 2025. The popularization that began in 2017 continues to develop in big steps. Every person in the world already knows about cryptocurrencies.
Maybe a lot know crypto at that time, but I don't think all of them will use crypto in their daily lives. Those who are residing in rural or remote areas will still prefer to use their fiat money, I guess. There is a large percentage living on this Earth that are not yet tap by electricity, so I doubt they will be part of this blockchain revolution.
Who knows that will be more in demand by 2024? Let's not close the doors foe these coins, and yet if technology became more advanced during thas year nothing is impossible to happen. Blockchain is not a stagnant technology, that's there's always software updates due to ongoing developments. Fiat money will be just an option in the future, and digital currency will be more valuable.
