According to some reports that most bitcoin mining are now in the US, Canada and China. Banning bitcoin now will force money into gold and other commodities, further driving up inflation.
I don't see banning bitcoin as having much effect on the price of gold or other commodities.
Plus by banning bitcoin, we should see bigger benefits globally from:
1. Less money laundering by criminals
2. Less electricity usage and therefore lower electricity costs overall
3. Bitcoin mining chips use up semiconductor production capacity. But now there is a global shortage of chips which is affecting production of cars, smartphones, computers, etc. That is a huge driver for inflation.
4. Fewer carbon emissions when processing transactions
I think banning bitcoin would be a huge boon for the global public good.
Remember that the only advantage of Bitcoin over a regular currency is that it is anonymous, which is a godsend for criminals and tax evasion
