RE: Hate putting private keys into websites? Introducing Steem Keychain!
We look forward to implementing keychain on https://steempeak.com we are big believers in it.
Our partner site https://peakmonsters.com has already been using Keychain for over a month now and it's been a raging success. Specially with people who buy cards frequently it makes it much easier and we believe much safer. (unless you often walk away from your laptop in public places)
