In my opinion it is fitting for all current governments to boost the popularity of cryptocurrency (Bitcoin), because Bitcoin can increase the economic growth of human resources in all parts of the world, the existence of Cryptocurrency can be a business opportunity for all governments to be able to make their own coins, so they can compete in this industry
For the governments, the level of economic growth which is expected as a result of cryptocurrency adoption is not enough to make up for the loss of capital controls than can result from it. But I can tell one thing. Cryptocurrency in this decade is similar to what internet was during the 1990s. Those countries which tried to block the spread of internet back then suffered enormously in the next few decades due to losing out in competition. The same is going to happen this time, with the cryptocurrencies as well.
