Certain governments may try because it will threaten their state sponsored currency but I believe they will ultimately fail.

Fewer people are trusting banks and governments and that is manifesting in the popularity of cryptocurrency (which will increase!). Look in places such as Venezula and you will see people who will never trust fiat again. South Korea did crack down but have already been surprised at the outrage and general contempt for the persons in government responsible.

Like your post, just wanted to share my thoughts!
