You have to understand what exchanges are and are not. An exchange is a central point where owners post collateral and thereby join and trade on the exchange. The exchange backs the trades with their solvency and reputation, but it’s not a barter system, and it’s not free: the exchange has to make money too. Look at the Comex, which reaches back to the early history of commodities exchange which was founded to match buyers of say, wheat, like General Mills, with producers, the farmers. But why not just have the farmer drive to the local silo and sell there? Two reasons: one, unlike manufacturing, harvests are lumpy. To have everyone buy or sell at one time of the year would cripple the demand for money in that season. This may be why market crashes happen historically at harvest when the demand for money (i.e. Deflation) was highest. Secondly, however, suppose the weather turned bad: all farmers would be ruined simultaneously.
Suppose the weather then recovered: the previous low prices are erased and any who delayed selling would be rich. This sort of random, uncontrolled, uninsurable event is no way to run an economy, so they added a small group of speculators into the middle. You could sell wheat today for delivery in June, and the buyer would lock in a price. This had the effect of moderating prices, insuring both buyers AND sellers, at the small cost of paying the traders and speculators for their time, basically providing insurance. But the exchange is neither buyer, seller, nor speculator. They only keep the doors open to trade and vet the participants. What’s not immediately apparent is these Contracts of Wheat are only wheat promises, not wheat itself. Although amounts vary, almost all commodities trade contracts in excess of what is actually delivered, and what may exist on earth. I mean the wheat they’re selling, millions of tons, haven’t even been planted yet. So they are synthetic wheat, fantasy wheat that the exchange is selling.
A Bitcoin exchange is the same thing. You post your Bitcoin to the exchange, and trade it within the exchange with other customers like you. But none of the Bitcoin you trade on the exchange is yours, just like none of the wheat traded is actual wheat moving …read more
