I am thinking of starting a brokering business, introducing Bitcoin buyers and sellers, and providing a safe escrow service for the transaction. This allows people to trade without affecting the price out of their favour on the exchanges.
I only know a little of this, but what I'm learning is that finding the bulk sellers is harder than finding the bulk buyers, The larger sellers might have coins from revenues arriving over a period of time (either mining or from sales to customers who pay using bitcoins). This is in contrast to the bulk buyer who arrives and wants to purchase the full amount in a single transaction with little delay, and at a level somewhat close to the current spot rate.
So in order to have access to the seller's supply there needs to be capital so that the seller will never be turned away whether or not a buyer is already lined up for those coins. The unsold stock may get converted to USDs and parked at an exchange until a buyer arrives, so as to protect against exchange rate risk, but that still is a capital intensive operation.
