Actually only a small part of the "government" are aware of BTC threat and most of them are still lenient on it and perhaps dont know about satoshi at all.
I'm not sure about that, since each country have a minister that related to economy, technology, or social which the minister has to know about society issues that can give effect to his work like bitcoin.
There is a difference between "heard of" and "know". Basically most people heard of
BTC but that doesnt mean that they know the actual meaning of it and/or purposes of it. Most country even viewed
BTC as rather an asset, goods or trading instrument which ofcourse they thought that it is harmless and not a currency that posses threats to their their economical system.
Some country banned
BTC because they knew the risk of it, some country do support
BTC and most country are being on the gray zone for it because they have absolutely less knowledge about what it is and rather just treat it like goods instead
Its up to the government if they want to know deeply or just heard of. But, if bitcoin affected the country economic system, the government won't just stay and let it be happen. Don't underestimate the government, we don't know what really the government will do about bitcoin behind us.
