Visa, Mastercard, Stripe, eBay, and Mercado Pago have withdrawn from the Libra Association, a project led by Facebook to create a global cryptocurrency. The withdrawals come after PayPal left the project a week earlier and deal a significant blow to Libra's plans. The companies cited regulatory concerns and a lack of clarity on the project's future as reasons for their departure. The Libra Association is set to hold its first official meeting in Geneva, where the remaining members will discuss the project's next steps.
