- allow an explosion of ETF's, including levered ones, to begin trading. With futures you can now hedge out your bets so it should, at least in theory, be easier to find a counter party to write you a swap against bitcoin volatility. It also lays the ground work for the SEC to see a functioning market for these products which they ahve said is a prerequisite to allow bitcoin ETF's to trade.
- give some rules around what's considered a fork and what should be ignored in the bitcoin world. Each of these products will provide some "adult" guidance to other markets as to which alt coins, forks, etc should be considered vs ignored.
From an implementation perspective there are two differences I see between the COBE and CME implementations.
1) The CBOE’s contract size will be based on a single bitcoin, while the CME’s contract size will be based on five bitcoins, a current notional value of more than $50,000.
2) The CBOE’s contracts will be cleared by Options Clearing Corp. while CME will clear its own futures. The CME has estimated that initial margin on the contracts — or the amount of collateral set aside relative to the value of a trade — may be as high as 30 percent, an unusually high amount.
