Not sure I follow the question exactly but this graph shows the daily Volume across different coins with market cap gt 1bn

The big blue dot in the middle is the daily volume on USDT which clearly shows a large appetite for a pegged asset.

The issue with SBD is the market cap is around 30m with a daily volume of close to 10m (today). I wouldn't me surprised if it was just downright manipulation keeping the price high. Steem volume (the underlying asset has a 14 million daily volume, that doesn't add up). If SBD had a market cap in the 100s of millions then I am speculating that it would be more stable. But it's never going to have this until we have some way of trading it outside of the Steem System. We need wallets and ways to spend it.

At the moment part of its utility is supposed to be as a trade-able liquid asset but you can only spend it on Steemit with the exception of using it to speculate on exchanges.
