Hey @billybeluga, Cryptokitties is a new game thats kind of like pokemon but each kitty is worth real money. You breed cats with good genes (cattributes) to make cats with even better genes and sell them for Ethereum. MetaMask is a safe platform to use and easy to sign up to, it involves installing the chrome plug in that can be found in this link: https://chrome.google.com/webstore/detail/metamask/nkbihfbeogaeaoehlefnkodbefgpgknn?hl=en

You can pay money into your account using coinbase or shapeshift, I personally use coinbase but the fees are pretty rough so try to send larger amounts infrequently. I will be making regular articles on which kitties are best to start with and how to begin breeding. For any other information let me know, I'd be happy to help 😊
