Could you have a “pay with bitcoin” button for your Uber sometime soon? The WSJ reported today that eBay’s payment unit Braintree is considering accepting bitcoin. Apparently the PayPal subsidiary has spoken to several companies including Coinbase about it, although there is no deal or timeline for implementation yet. The deal is allegedly limited only to Braintree — whose clients include Uber and Airbnb — and would not include eBay or PayPal yet. Braintree wouldn’t be the first business of its kind though to embrace the virtual currency; companies like Stripe and Shopify have already jumped on the bitcoin bandwagon.
