$1.053 USD is a 5.3% variance. As i check on coinmarketcap now i see it listed at 1.04usd or a 4% variance.
Compare that to Tether (USDT) at 1.00 USD and NuBits (NBT) at $ 0.997296 or .27% variance.

NuBits is a superior system as it more closely maintains the peg (according to data on CMC)and does not have the systematic risk associated with BitUSD and other bitshares collateralized assets.
