Dogecoin has 5% of inflation a year forever through POW mining and 95% of miners dump their coins.
Not according to Wikipedia:
"Dogecoin has a fast initial coin production schedule: there will be approximately 100 billion coins in circulation by the end of 2014 with an additional 5.2 billion coins every year thereafter." --
http://en.wikipedia.org/wiki/DogecoinThe 5.2 billion coins will actually result in less and less inflation every year, since the total dogecoin supply will increase. So it's not a compounded inflation rate like Reddcoin.
I will test Dogecoin a bit. I tested Reddcoin but I'm starting to wonder if maybe Dogecoin is better as a social currency after all.
