Amazon has just announced the expansion of its virtual currency system, Amazon Coins, to the entirety of the Android ecosystem. Amazon Coins were previously limited to users of Amazon’s own Kindle Fire tablets, but now it doesn’t matter what kind of device you have.

Amazon Coins, the new virtual currency from Amazon that was announced back in February, makes its public debut today. It’s available to Kindle Fire owners who use the Amazon Appstore to download their digital content, and every user in the United States gets 500 coins — worth $5 — free to get them started.

Amazon has today announced a new virtual currency that will be used inside apps and games developed for its Kindle Fire tablet family. Called “Amazon Coins” and set to arrive in May, Amazon believes the move is “another substantial opportunity to drive traffic, downloads and increase monetization even further” for developers.
