There are already a boatload of stablecoins put there and now another basketful has been added, the stablecoins in the market works just fine for me and I don't think I would want to add more to my collection, I am especially partial to the ERC-20 USDT and the USDC stablecoin and TUSD, haven't used any other stablecoin though, those ones are listed in most top exchanges.
