One of the most popular personal financing tools around is now even more well-rounded thanks to a recent update that adds support for Bitcoin. With help from Coinbase, Mint now allows Bitcoin users to keep track of their cryptocurrency account balance and transaction history just as they would with any other currency.

Mint group product manager Vince Maniago pointed out that by adding Bitcoin visibility, Mint becomes the only personal finance and money management tool enabling users to view those transactions. The added feature will help server customers' changing financial needs and can provide users with a more complete financial picture, he said.

With more than 12 million Bitcoins in circulation and some 60,000 merchants now accepting it as payment, it was simply something that Mint said they could no longer ignore. With more than 14 million users, Mint felt it was time to take action and support the currency as it becomes more legitimate.

All that's needed to bring your Bitcoin history into the mix is your Coinbase API key. It's worth pointing out, however, that Mint is treating Bitcoin as an investment account. So instead of just another checking or savings account (cash), your Bitcoins will sit alongside other investment accounts like mutual funds and stocks.

Mint is free to download and use from the App Store on iPhone, iPad and iPod touch as well as for Android smartphone and tablets at Google Play and on the Amazon Appstore. Mint is also available in the Windows Store for Windows 8.1 and the Windows Phone Store for Windows Phone 8, we're told.
