Someone has already created a cryptocurrency for the SAFE Network. It's called ThankYouCoin. It's just an example coin you receive for testing the wallet and can test sending to other users. The wallet is currently setup to hold credit card, passwords private public and private key pairs, 2FA Codes, Safecoin Wallet and ThanksCoin Currently. The TY Coin is spelled differently in once instance and i'm unsure which way is the proper one. I'll have to check the Weekly Development Forum post below to see which is right.
