You can now add funds to your Microsoft account using Bitcoin, but only if you live in the US.
The money can then be used to purchase games, apps, music and videos on Xbox consoles and Windows devices.
Bitcoin has slowly risen in popularity from its origins as an obscure digital currency to a recognised payment method - even at some high street chains.

Microsoft is the first of the major platform holders to allow payment with the currency, however.
We've asked Microsoft if the currency will also become available as a payment option in the UK.
