The exceptions to withholding for Capital Gain Dividends and short-term capital gain dividends do not apply to (A) distributions to an individual foreign shareholder who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution and (B) distributions attributable to gain that is treated as effectively connected with the conduct by the foreign shareholder of a trade or business within the United States under special rules regarding the disposition of U.S. real property interests as described below. The exception to withholding for interest-related dividends does not apply to distributions to a foreign shareholder (A) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (B) to the extent that the dividend is attributable to certain interest on an obligation if the foreign shareholder is the issuer or is a 10% shareholder of the issuer, (C) that is within certain foreign countries that have inadequate information exchange with the United States, or (D) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign shareholder and the foreign shareholder is a controlled foreign corporation. If a Fund invests in a RIC that pays Capital Gain Dividends, short-term capital gain dividends or interest-related dividends to the Fund, such distributions retain their character as not subject to withholding if properly reported when paid by the Fund to foreign shareholders. A Fund is permitted to report such part of its dividends as interest-related and/or short-term capital gain dividends as are eligible, but is not required to do so.

A Fund may cover its sale of a call option on a futures contract by taking a long position in the underlying futures contract at a price less than or equal to the strike price of the call option, or, if the long position in the underlying futures contract is established at a price greater than the strike price of the written (sold) call, the Fund will earmark/segregate liquid instruments equal in value to the difference between the strike price of the call and the price of the future. A Fund may also cover its sale of a call option by taking positions in instruments whose prices are expected to move relatively consistently with the call option. A Fund may cover its sale of a put option on a futures contract by taking a short position in the underlying futures contract at a price greater than or equal to the strike price of the put option, or, if the short position in the underlying futures contract is established at a price less than the strike price of the written put, the Fund will segregate cash or liquid instruments equal in value to the difference between the strike price of the put and the price of the future. A Fund may also cover its sale of a put option by taking positions in instruments whose prices are expected to move relatively consistently to the put option.
I have worked with the CME in the past on product development (specifically CDS futures) and from my experience, they would not have missed anything this simple.  In fact, while I am not a huge fan of the concept of Bitcoin futures, as currently implemented, I do not expect any errors in the operation of the CME or CBOE futures contract.  I am sure that regulators will be questioning them on the back of the OKEX, as they should, and I am also quite positive the exchanges here will pass with flying colors.
Speculating and hedging bitcoin with futures has never been easier. Spot has lower leverage which means you have to risk more of your capital with exchanges. Margin fees are very expensive on Bitfinex and Kraken when you are borrowing funds and paying up to 0.1% per day to be in a position. Futures contracts on the other hand have no holding fees associated. You pay a fee to enter the contract, and you pay a fee to exit the contract. Your profit or loss comes from the change in the price you pay.
RD – Restricted default. ‘RD’ ratings indicate an issuer that in Fitch’s opinion has experienced an uncured payment default on a bond, loan or other material financial obligation but which has not entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure, and which has not otherwise ceased operating. This would include:
Although certain securities exchanges attempt to provide continuously liquid markets in which holders and writers of options can close out their positions at any time prior to the expiration of the option, no assurance can be given that a market will exist at all times for all outstanding options purchased or sold by a Fund. If an options market were to become unavailable, the Fund would be unable to realize its profits or limit its losses until the Fund could exercise options it holds, and the Fund would remain obligated until options it wrote were exercised or expired. Reasons for the absence of liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain options; (ii) restrictions may be imposed by an exchange on opening or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or the OCC may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options) and those options would cease to exist, although outstanding options on that exchange that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms.
Margin-trading is what provides the real reward and potential in daytrading bitcoin. You will be able to access the leverage to profit well from relatively small moves in BTC/USD price. High risk, high reward, high potential for loss. However, you need not use Futures only to speculate, hedging on lower leverage is also a great use case for Bitcoin derivatives if you just want to defend your coins.

Unlike cloud-storage provides, Sia’s tech gives you all the keys to your own (encrypted) data, and mandates that no third party will control nor access your files.
Each Fund may enter into reverse repurchase agreements as part of its investment strategy, which may be viewed as a form of borrowing. Reverse repurchase agreements involve sales by a Fund of portfolio assets for cash concurrently with an agreement by the Fund to repurchase those same assets at a later date at a fixed price. Generally, the effect of such a transaction is that a Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while a Fund will be able to keep the interest income associated with those portfolio securities. Such transactions are advantageous only if the interest cost to a Fund of the reverse repurchase transaction is less than the cost of obtaining the cash otherwise. Opportunities to achieve this advantage may not always be available, and a Fund intends to use the reverse repurchase technique only when it will be to the Fund’s advantage to do so. A Fund will segregate with its custodian bank cash or liquid instruments equal in value to the Fund’s obligations with respect to reverse repurchase agreements.
Some Centra investors have their doubts, and a plaintiffs' law firm has brought a class action complaint against Centra demanding the investors' money back. The complaint is fun -- Centra had a “Blog/Media Bounty” program to "Reward Experienced Writers who write quality Reviews, Articles About the Centra Project and the ICO crowdsale" -- but not that fun, because the plaintiffs' lawyers don't actually need to prove that Centra was a scam. Their job is much easier: All they need to do is prove that the tokens Centra sold in its initial coin offering were securities. If they were securities, they were sold illegally: They were offered publicly without being registered with the Securities and Exchange Commission, or being exempt from registration. And one remedy for the illegal sale of securities is that the buyers can demand their money back -- whether or not Centra is legitimate, whether or not it is actually using the money to build a cryptocurrency debit card, whether or not it made any misleading statements in the ICO.

​The price of the futures contract can deviate from the underlying price of bitcoin on spot markets, which can vary based on sentiment. But in the end, at expiration of the contract, the contract MUST settle at the price of spot. So you need to watch the main spot market price movements because the futures contracts will track the movements underlying (sometimes leading, sometimes lagging, sometimes simultaneously). There are three Chinese exchanges worth following: OKCoin, Houbi, and BTCC; there are two Western exchanges worth following: Bitfinex and Bitstamp. Other exchanges that are currently less important but still worth keeping an eye on are: ItBit, Coinbase, OKCoin USD, BTC-e, and Kraken (which has the largest BTC/EUR orderbook as of December 2015).

Recent bitcoin futures contract announcements from CBOE, CME, and Nasdaq have generated tremendous interest in digital assets. Bitcoin futures have been highly anticipated as they will provide traditional financial institutions with one of the first opportunities to meaningfully participate in the digital asset space via a regulated investment framework. It is an opportunity for Wall Street to catch up with Main Street on bitcoin. With the impending launch of U.S.-listed bitcoin futures, investors may wonder what the bitcoin futures curve might look like. Using information from existing digital asset derivative trading platforms such as Bitmex, OKCoin, CryptoFacilities, and BTCC (all exchanges outside of the Commodity Futures Trading Commission purview), MVIS Research has constructed an approximate curve based on non-U.S. bitcoin futures trading on these exchanges. These are real trading platforms revealing real volume.
There's a lot of ins and outs which can get confusing in arbitrage trading. We won't go into the technicals of why futures contracts trade at a premium to spot price. You can read a full explanation here. If it's not of interest to you, all you need to know is that there's a tendency, the further out in time the futures contract expires, for the premium to spot to be higher and higher in nominal percentage terms.
