Good article. Less than 10 years ago, Russia, China, and Iran wanted to find a way to have their fiat currencies [or another] supplant the USD as the default world currency. They failed.
Then someone [not mentioning any names, but most of the miners are from there] got this thing called Bitcoin which fools people who hate fiat [or enjoy buying gambling tokens] to support a replacement fiat currency for the USD.
No, Bitcoin is not that currency.
But Bitcoin is the medium of exchange which permits the wealth in USD to leave and go into other currencies.
It is a wealth transfer from those who held USD as a fiat to people whose interests are aligned with making another currency the default fiat currency.
