The USD is driving Bitcoin out of circulation in the USA.

People say Bitcoin needs to be spendable in the US, but even if it is - it might not gain much traction.

Why? Because in an economy like the US/USD paradigm it seems that people understand that their money is becoming worth less every year, so they invest it for a return somewhere & DCA.

They do this on a large scale with savings, including retirement accounts.

This should hold as Graham's Law states, good money is hoarded - bad money is spent.
