BitShares volume is being calculated by adding all the Bitshares assets trading volume, like bitUSD, bitGold, bit silver, bitBTC and bitCNY. Just an observation. So today the BTC and fiat volume was $40K less than what coinmarketcap is broadcasting.
I'm not sure if that is the case, but:
If each market pegged BitAsset (BitUSD, BitCNY, BitEUR, BitGOLD, BitSILVER, BitBTC)
locks 300% of bitshares value as collateral (at the moment of creation),
isn't if fair to consider locked bitshares when talking about BitAssets?
