These countries who ban bitcoin didn't understand the whole capabilities of it. Most probably their intentions was not good and commendable for their allies, considering the fact that bitcoin was a decentralized asset. Fiat economy is really different with unregulated currency and example of that bitcoin and all crypto coins that's separated from Government control.
Actually they do understand, and it just happened to be that it goes against them. Imagine that you're governing a lot of people and your people would use something that is under your radar/observation. Pretty much you would think that they are doing something against you.
The part that they don't understand is that people need the privacy in their own money, not to be regulated by someone that is at risk of being taken away from them.
