well,
lot of goverment are interested in implementing bitcoin, or their own cryptocoin.
but i can still see in the future that mega miner or gov start sending sattelites or microsatellites to mining bitcoin or their crypto coin.
Other governments, like Canada, tried creating their own digital currency. But they are not decentralized or open source, so they are not trusted and have few of the features that are attractive about bitcoin. There is really nothing a government can do about bitcoin.
because the electricity will be free and can be operated without internet, it will be like gps for cryptocurrency.
