Either.
You don't get my point. I know Long. My point is : What is the Long process in BitUSD? You buy BitUSD by what? Flat money or BitShare?
OK, Let discuss the two cases:
1. You buy BitUSD by USD.
Where is your BitUSD ? You have to generate them first, right? And in order to generate them someone else has to short BitUSD. Is that correct? If so, and there is no market-maker, if everyone thinks BitUSD will rocket into sky and no one short BitUSD, you can not generate BitUSD !
2. You buy BitUSD by Bitshare.
What will happen to the Bitshare?
