As long as the country still exists with the government, the most power will be under a centralized system. The decentralized system will only be implemented in some industries or parties, not for all. It may be only available in some countries.
Well, if it is about the technology using a decentralized system, it will also depend on what kind of technology sectors, if it is about the very important data, will it be decentralized? I think not.
But then, what is uncertain is regulation, can cryptocurrency grow into a multi-trilion market without the proper regulations?
It will depend on how the country accepts the cryptocurrency. They may be available to be a partnership in the case of legalizing crypto without any hard rules and regulations. But, there are also some countries that are not willing to fully legalize the crypto. So far, this may be the problem faced by the crypto world and technology.
