The Long position is always paired with a short position.
To Short BitGold you borrow it like the prior example, and then sell the BitGold you receive to the individual who goes long. Now to cover your short position you must repurchase it from the Long.
Can you describe the long process just like the short process? It won't take you a long time and I believe it will clear the mist for many people.
The Long and Short process are the SAME the person who borrows BitGold into existence is LONG BitGold until he sells the BitGold at which point he becomes SHORT.
Example: If I borrow $100 from you and keep it then I have $100 in my bank and a $100 debt to you on my books. I am long and short and thus neutral. If I then spend that $100 I am now short because I no longer have $100 in my bank, but I still owe you $100. The person who holds the $100 with no debt is LONG USD.
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?
