The problem with bitUSD is that it is only available on bitShares. That and it is only backed with bitShares. I think it will work best in an environment where bitShares is number one. That isn’t likely to happen. As long as Binance and Bittrex have USDT pairs Tether will rule. That being said I’m not ruling out a USDT scandal. Although, I think the fear around USDT is a little overblown. Since Bittrix owns Tether they would have a lot to lose in a collapse or USDT.
