Instead of earning bitcoins, what BitMaker actually does is allow you to earn are satoshis. 'What is a satoshi?' more than one confused reader will ask. A satoshi is, in short, the equivalent of a cent for bitcoins. But, a satoshi is worth much less than one one-hundredth of a bitcoin.
With BitMaker you can earn 500 satoshis every half hour. That being said, you can also install other apps in order to earn more satoshis. All the money you earn will go directly to your Bitcoin wallet, which you can configure in app's settings.
BitMaker is an interesting app for bitcoin enthusiasts, since it lets you earn a little bit of extra money.
