Corion is holding its ico now. The coin attempts to solve crypto volatility a key issue of cryptoadoption. If Dash wants to become the Venmo of crypto it could learn from Corion.
Extreme volatility and underlying deflation makes crypto suitable for speculation, for trading and a store of value but bad as a currency. Corion addresses this by making the coin inflation rate variable.
Cryptos are volatile because the rate of adoption is always increasing at variable rates. The fixed supply of most crypto also makes them inherently deflationary. Corion addresses this by changing the coin emission rate between 0-2.5% per day to hold the value at $1. If the coin falls in value fees begin to be burnt leading to a falling supply. This may sound like a little but inflation could range between 0 and over 1000 percent ( due to compounding). This seems likely to be much more stable if not precisely tied to the dollar.
Corion rewards its investors by giving them the inflation (this is more complicated than a pure proof of stake). Instead of making (or losing) money on coin appreciation, Corion holders should receive more coins (interest?) if the coin proves popular. Who knows if this will occur as planned but it's an interesting idea.
Dash hopes to be used as a currency but it's better suited as a store of value. The price of dash has skyrocketed this year. While the Devs are focused on getting more people to use dash but you would have to be stupid to sell a rapidly appreciating asset for a cup of coffee. Dash needs a stable value component if it want to win the mass adoption battle.
