How could you initiate a new Exchange Market? Supposing I want to "initiate" an exchange market. Is the only way to get some bitcoins IN  to buy them from another exchange and trying to sell them? (or to wait for people starting trading, correct?)
Thanks
As the name "exchange" suggests, an exchange does not buy or sell bitcoins themselves. They merely function as an exchange between sellers and buyers.

So what you will have to do is wait for people to start trading. But people won't come by themselves, so you will have to give users a reason to come to you instead of an existing exchange. It may also help to trade on your own site in the beginning both to not completely rely on new user's transactions and to generate some trade volume.
