Indeed, 10 million is conservative whennya consider governments will have to bow to bitcoin and begin their own btc mining.
Russia government is already aiming to have 20% of the bitcoin mining capacity.
In the USA the federal reserve banksters wont go down without a fight, expect some more deep state dirty tricks like what they did to Ross Ulbricht.
The government will never bow to Bitcoin, as much as I wanted to see it but that is the reality. Instead, the Government will do whatever in their power to regulate Bitcoin. And as for $10m per Bitcoin price, I think it is an exaggeration since it is not compulsory for everyone to have Bitcoin or satoshi, the demand that we are imagining is far too large than the actual statistics.
