What kind of buy support does BitUSD have?
Well, I decided to do a little research on my own question. Below is a screenshot from just now, from the BTER BitUSD/USD market.
If you are willing to accept a 2% loss, you can sell $200 instantly. If you are ok with a 3% loss, add another $213 to that. At a 4% loss, sell another $162. If you have more than that to sell, it won't be easy. Also, even if you have just $10 to sell, you still won't get the pegged price, because $1000 in sell orders must be cleared out before the market can move to its "pegged" value. This could be inhibiting merchant adoption.
This makes me realize why NuBits has so much more trade volume than BitUSD right now. It's tough to compete against $140,000 of pegged buy orders with $500 (at best). It's an uphill battle.
