Thought this might be a good starting place to announce

http://www.predictcoins.com/The game is currently under active development, with many more features in the works.
Any thoughts, ideas or suggestions are much appreciated

Thanks!
That's a great looking user interface. Well done. Is there a reward for being a good guesser, other than community pride?
