Ah yes, the Bitcoin, the digital currency that's been through a lot in the last couple of years has finally become a staple of online commerce and while the currency is still struggling to become widely recognized along with the Dollar and the Euro, it seems Google is happy to accept it as any other currency. Since Google launched their Knowledge Graph along with Google Now, it's been even easier to get quick information with your voice or a simple search. There's no need to trawl through a bunch of links for a lot of things now, which is great for getting info quick when you need it.
For currency, this has worked great for a long time now, and you can easily ask how much the dollar is worth against the pound and simply be told straight away, without any fuss. Now, this works for Bitcoin as well. As a result of the partnership between Google and Coinbase, Google will now tell you how much a Bitcoin is worth with a simple command. This works no matter what you're using, be it the web, your Android Wear watch or the smartphone app. Saying "bitcoin price" will give you the price for one Bitcoin in your local currency, and things follow on nicely like "2 Bitcoin price" and so on. If you want to get a price for Bitcoin in a different currency you can just add that to the add of your command and it'll work just as it would for any other currency.
While not that exciting for those of us that don't dabble in Bitcoin, this is a nice addition to Google's Knowledge Graph and works great on mobile, and if you're in need of a quick reference, Google will now make that happen. As with every currency calculation, this Bitcoin addition to Google isn't going to be 100% accurate and due to the nature of Bitcoin, you should expect a few more fluctuations than normal.
