This article is 100% BS. Go anywhere in Africa, the Middle East, Turkey, or South America, the US$ is king.
Ask a man selling his used car, anywhere in the world, if he'd prefer to be paid in $, Russian ruble or Chinese yuan. Besides the Swiss, all the world would choose $.
There is no doubt that the US dollar is still used globally, not only because the United States is a powerful country, but also because of global use, global recognition, and global exchange rate. Just because we are used to it. Of course, the emergence of Bitcoin will change some things, but for now, the US dollar is still the mainstream currency.
The very strong USD position certainly makes everyone think of making USD as a transaction, the USA central bank always keeps the USD's strict circulation so that it makes high trust for USD holders, if they leave the USD it will use currency from other countries which certainly does not guarantee it can be more good than USD.
