The American public and global community, the president argued, should use the "reliable" U.S. dollar instead, as he called for more federal regulations of peer-to-peer financial transactions.
Rep. Maxine Waters (D-CA), who heads the House Financial Services Committee, said that by introducing its own currency Facebook was "continuing its unchecked expansion and extending its reach into the lives of its users".
Facebook declined to comment on Trump's concerns.
Hong Kong protesters take aim at Chinese traders
Major demonstrations in the past month against a proposal to change extradition laws have reawakened other movements in Hong Kong. Sheung Shui resident Ryan Lai, 50, said: 'Our lovely town has become chaos.
It is also a fact that America's arch-rival, Russia, is venturing into the crypto space, with the aim of substituting United States dollars in global trade.

"[This] makes the case for Bitcoin even stronger".
