Even weirder regarding Poloniex is I thought Circle were putting together their own stablecoin about which nothing has been heard since it was mentioned.
I think they realized that they won't ever be able to reach USDT's global penetration level and for that reason refrained from launching their own coin, which we should be happy with, especially with how we're seeing these 'stable coins' pop up more frequently nowadays. Bittrex and Binance have listed both USDT and TrueUSD, which is retarded. How many of this garbage does an exchange need?
USDT (and basically all other fiat backed stable coins) is the perfect 'scam' with how you (as issuer) for sure know that at least 50% will never be converted back to fiat since it's needed to provide liquidity to exchanges as Binance, OKEx, Huobi, Bitfinex, etc.
