What I do not understand, @davidhay, is WHY they would do it. Most people working in Crypto (or anywhere) do it for financial gain. A few do it for technological advancing for the human race (thanks Mr. Buterin).
Tether does neither. They don't make money OR progress the Blockchain-Technology. So why would they spend all this time making it. That's my primary concern.
Bridging the gap, offering stability against volatility, any niche coin may have a future ahead of it. Why does iohk develop only open-source projects with tailoring to specific projects left too project specific developers? Conglomeration of tools is strength in a decentralized network, as is a niche market.
