18.Why same options have quite significant price differences across exchanges?
As we have pointed out, there is no theoretically correct option pricing model. Option price differences on different option trading exchanges reflect different risk appetites of option underwriters and option buyers. Unlike stocks or other financial products, option underwriting and trading usually is segregated, there is no central clearing house for options. What’s more, so far, centralized cryptocurrency exchanges have no regulatory authority oversight on them. Centralized exchanges have inherent risks. Therefore, it’s not surprising to observe that the same option can be traded at quite different price levels.
