Key Coin (KEY) started in 2014 and finished in 2014, with a total supply of 949 thousand coins. The team/founder is hidden, The main reason this coin was listed is desertion.

(from old site) KeyOS beta testing is nearly ready and we are also building an encrypted messaging system, while standing strong to the constant attacks on morale. We are all still working hard, as of today there are currently twelve people actively working on the project. We will wait for the FUD to die down, or create a new moderated thread with an updated ANN soon before we post any major updates. A project roadmap and description of each team member's role in the project will follow. Thank you for following KeyCoin.
