The President also criticized cryptocurrency's role in facilitating crime and drug trafficking.
Testifying before the House Financial Services Committee earlier this week, Federal Reserve Chairman Jerome Powell said the proposed coin "raises many serious concerns regarding privacy, money laundering, consumer protection and financial stability".
Facebook has pledged to deliver a stable virtual currency that lives on smartphones and could bring over a billion "unbanked" people into the financial system.
Trump then went on to explain how if Facebook and other companies want a virtual currency, then they should seek a banking charter and become subject to banking regulations.
Mr. Trump said, "Cryptocurrency is not money, and whose value is highly volatile and based on thin air".
Indicating a preference for traditional currency, the President added "we have only one real currency in the U.S., and it is stronger than ever, both dependable and reliable". He further added that it is the most dominant currency in the world, and assured that it will remain this way.
Why Does Donald Trump Hate Bitcoin And Cryptocurrencies? She recently called on Facebook to halt its plans to launch Libra, prompting a personal written defense from project head David Marcus.

What none of us know exactly is the scale of the illegal operations being carried out by Bitcoin or other cryptocurrencies.
Among investors, however, nearly all the attention was on Trump, with many in fact thanking him for drawing attention to the industry and proving it did not need his support.
