"Much as a bank like Goldman Sachs runs software to track price fluctuations as it juggles billions of dollars, Coinbase uses its hedging software to track all of the bitcoins it manages, deciding when to buy and sell bitcoins and adjust its exchange rate in an effort to minimize risk.
Goldman, where Coinbase’s Ehrsam previously worked, uses its software in an effort to make highly profitable trades, and Coinbase merely uses its system to protect its own position. But the inner-workings of the software are similar. “It’s algorithmic trading,” says Coinbase CEO Brian Armstrong. “It hedges that exchange rate risk in the background, every day.”
