There are still some rural places in this world, so it will be hard for them to adopt the new system if this will be implemented in the future, which I hope won't happen, and even those person in provinces will also get mad if those things happen.
I live in the province but I think people could be used to those changes. The only problem we have right now is that obviously, the government can't afford that technology, that development. In the future though, for sure, we would be able to see a crypto currency as the main currency but for sure that would not be a decentralized currency.
I think it is not that the government can't afford the technology, for me, it is the government who don't want to accept cryptocurrency because they aren't that knowledgeable about it. Based on my observation, I think that their mindset about cryptocurrency is, it is full of fraud and scammers. That's why we should first let the government know that the benefit of cryptocurrency is somehow focused on the economy and the market. We can start just by promoting it in some business or platforms that many people can see, once they got curious about that then that's the first step. Also, crypto is not the enough yet, because it still lacks some ability to replace fiat currency that is used for so many years, it is not that easy to replace it with cryptocurrency, may be soon.
