He either has no understanding of how United States regime works or he thinks his audience doesn't understand it. To be honest if he had said "he would end the war with China" it would have been an impossibility closer to reality than saying this about bitcoin.
1. He has to first tank the dollar price where the exchange rate would be something like 1 Venezuelan bolívar is equal to 1 US dollar thanks to the massive amounts of dollar they've printed over the past 20 years alone, not to include the circulating supply before that.
2. The US economic structure has to change. They can no longer print money whenever they want to. Like the $10 trillion they printed for the War in Iraq and Afghanistan. The trillions they printed in COVIC pandemic and the $3 trillion they printed in the past couple of months alone to battle the US recession and fund the proxy war with Russia!
This dude is speaking in a way that one would think that he has not spent a single day in US political scene!
By the end of this month most probably another "war" will begin between the US government and the US parliament over the second raising of the US debt ceiling.
Where does he plan on bringing all this money if my some magic he won the election? It's not like the US regime's foreign adventures are going to stop to reduce its ridiculously ginormous expenses. He would have to print money out of thin air like his predecessors.
There's a reason US regime killed the Bretton Woods system. The system is broken and it is impossible to fix it without a literal revolution in North America and possibly a civil war.
