Very few of these are stable coin. Bitcoin Cash? Come-on it is MORE volatile than Bitcoin. DigixDAO is not stable. Look at the chart. Nothing based on gold is going to be stable as gold is a very volatile commodity.

So we have currently DAI, USDT, and TrueUSD. DAI isn't on any real exchanges so basically its USDT and TUSD. USDT is very likely a fraud and currently under investigation by the Treasury Department.

Kind of slim pickings in the stable-coin department. Clearly opportunity for someone to deliver a legitimate and trusted stable coin.
