Does Visa randomly give away a bunch of money every 10 minutes to those that made a purchase in the previous 10 minutes?
Would it be a bad thing for you if they did?
There are many alt coins that have lottery functions (lucky coin) and other proof of stake coins that reward you for "participating".
I'm familar with Proof-of-Stake, but it does the opposite. It doesnt reward any real participation, it rewards hoarding (instead of making transactions). Also, it makes the rich even richer, and thats just what Im trying to avoid here. With PoS you have more chance based on the amount of coins you own, while with this your chance does not depend on how much you already have.
check out freicoin... it has a 5% annual holding fee.
