PayPal has been coy about embracing virtual currencies so far, but it just took a big step toward welcoming them with open arms. As of today, the company's deals with processing firms BitPay, Coinbase and GoCoin let you pay with Bitcoin at North American online stores that both use PayPal's Payments Hub and accept digital cash. This doesn't mean your PayPal wallet can suddenly hold Bitcoin; the service says it's only moving "gradually" toward full support, and wants to see how things shake out. However, it should now be easier for many outlets (primarily smaller ones) to accept Bitcoin. Don't be shocked if some of your favorite internet shops flick the switch and give you an alternative to paying with old-school money.
