Introducing Lumen Bucks!
Lumen Bucks is a rewards app that rewards you Lumens for interacting with app ads, downloading & testing apps, or watching promos.
A little about the author: I launched a similar app named Coin Bucks in 2016, and over the course of the last 2 years I've paid out over $375,000 worth of Bitcoins to users. (See https://blockchain.info/address/1CoinBuxfL8JvwCVh98sn2kPt558EJph44)
If chosen for the Stellar Build Project I will promise to distribute a portion of the awarded lumens across users of the app.
Have fun earning and I look forward to many updates in the future!
