I read a lot in here about the market peg for bit asset...
I know what the concept means, but except for pre-defined market consensus, I don't see how it can peg to the USD value. Is market consensus a sufficient force to keep the peg?
My understanding of shorting is selling something you don't have (and borrow) for a fixed price in the future, betting the price will drop so you'll be able to buy it cheaper later and make a profit. (Am I right?) But how does shorting could get the value of bitusd to drop compared to usd and affect the peg?
