for now it seems that the government has not given too much support in cryptocurrency. Only a few countries have supported the development of cryptocurrency. If all governments in various countries have supported the development of cryptocurrency, then it will trigger cryptocurrency prices.
This will happen in time, actually right now a lot of countries are showing their interest to adopt cryptoccurency, its a good thing for cryptomarket. But don't expect the government to drop their fiat currency and move to cryptos because it will not happen. I just hope for a good regulations around the world so we can now use this technology without any problem.
