Facebook provided TechCrunch with new information on how its cryptocurrency will stay legal amidst allegations from President Trump that Libra could facilitate “unlawful behavior”. Facebook and Libra Association executives tell me they expect Libra will incur sales tax and capital gains taxes. They confirmed that Facebook is also in talks with local convenience stores and money exchanges to ensure anti-laundering checks are applied when people cash-in or cash-out Libra for traditional currency, and to let you use a QR code to buy or sell Libra in person.

A Facebook spokesperson said the company wouldn’t respond directly to Trump’s tweets, but noted that the Libra association won’t interact with consumers or operate as a bank, and that Libra is meant to be a complement to the existing financial system.
