Will Satoshi be happy about the idea of the government to adopt Bitcoin & using it as reserve?
We don't know what Satoshi would feel in this current situation, but we can assume that he is happy with ongoing developments happening with his creation. Also making it as a reserve on some powerful countries is good achievement since he created is now helping a lot of people globally also making it as a reserve will make it more stronger asset in the world.
Bitcoin is growing stronger and more credible around the world - and that's good.
The question is where this would lead in the long run.. Though without the adoption from big countries, as it was said, Bitcoin would probably not reach the state we are dreaming about.
