Tap the screen to earn more coins, upgrade your mining office and become a Bitcoin Billionaire! You know it’s good when a listed feature is to “unlock achievements by being awesome”.

You can play via the mobile app, or wager Bitcoins on the various fighters in the tournament from the app’s website. A great feature is that this game is provably fair.

Lawnmower – as a Bitcoin investment app, Lawnmower aims to help you earn Bitcoins by investing your fiat currency. You login to the app via your Coinbase account, sync your fiat bank account and then it goes to work. The concept is that the app rounds up your purchases to the nearest dollar and takes that pocket change and converts it into Bitcoin. Now instead of dropping a few pennies in the tip jar, you’ll be putting them towards earning cryptocurrency.
Fitcoin – we recently reviewed this app and this could be the next big thing in Bitcoin. Fitcoin aims to get you in shape – really good shape – by paying you Bitcoins the harder you work. It wants you to sweat and actually earn those coins. For all those Bitcoin miners sitting at their desks all day, this could work wonders.
GetGems – the app that pays you to text people. While this app deals with GEMZ as opposed to BTC, the currency is similar in that it is a decentralized cryptocurrency. What is does – whenever you refer someone to the app and that person becomes a new participant, you earn 25 GEMZ, which is roughly equivalent to $0.25 (which could be put into Lawnmower by the way…). You can also transfer crypto funds via the messaging service within the app.
