which means all are just betting on the fact that it might be great alternative to fiat but actually it's no where better than fiat at any level.
I believe it is a matter of infrastructure building. If they managed to build a solid network that is not prone to hacking and is easy to use, they will likely pivot to it as soon as possible since it offers better control over their fiat transactions.
They had no option than to invest in the blockchain but in a highly centralized way. The dilemma is tagging crypto illegal and creating a copy of the illegal and calling it legal.
I mean that should be expected. The government's main goal is to control the economy. I don't see why they will shy away to copy any new tech even if it was used by something that they deemed illegal. Some of them even fund privacy technology, probably to add another point of control over their people.
