Bitcoin Cash SV is the fork for Bitcoin Cash supported by Craig Wright, probably best know for his repeated and quite questionable claims to being Satoshi Nakamoto (smh). CW aside, it does appear that Bitcoin Cash SV may have some long term viability so we're adding support for it on BlockTrades as we're not in the business of picking fork winners.

Bitcoin Cash SV pricing varies widely accross exchanges due to deposit/withdrawal issues

A number of well-known exchanges are currently trading bitcoin cash SV without enabling deposits/withdrawals. This means the prices of the coins on those exchanges are likely to diverge from exchanges where deposits/withdrawals are functioning. For examples of this, see here (this is likely to change, so don't expect this link to matter in a few days):

But here's a screenshot at this moment:

BlockTrades can only rely on pricing from exchanges with functioning deposit/withdrawal capability

Note that bchsv is trading much higher on Binance (which doesn't allow deposits/withdrawals yet) than on Bittrex (which does). We therefore don't use pricing from Binance, because we consider prices from an exchange without functioning deposits/withdrawals to not accurate reflect real market conditions. Note that coinmarketcap IS relying on pricing from such exchanges when doing it's averaging of the USD price: this means that BlockTrades is currently valuing BCHSV at about 6% discount to the price shown on coinmarketcap at this moment in time.
