I have received my 1st Proof of Stake interest on Grain coin, had 100k and wallet was just open and unlocked for about 10 days now and received 147 coins, had it running on my mining rig as its on all the time.
We can imagine CASH works like this too.
The logo isn't quite right with 2 C C. Won't really ever see a logo with repetition in it, would be stylised. I hope no one minds my mate working on a whole design philosophy behind it, coin is still new and WIP, so things changing is a good thing.
