R-1 (low) – Short term debt rated “R-1 (low)” is of good credit quality. The overall strength and outlook for key liquidity, debt and profitability ratios is not normally as favorable as with higher rating categories, but these considerations are still respectable. Any qualifying negative factors which exist are considered manageable, and the entity is normally of sufficient size to have some influence in its industry.

The proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there's currently no standard form of it. Some cryptocurrencies use a combined proof-of-work/proof-of-stake scheme.[18]
ProShare Advisors believes that its compensation program is competitively positioned to attract and retain high-caliber investment professionals. The compensation package for portfolio managers consists of a fixed base salary, an annual incentive bonus opportunity and a competitive benefits package. A portfolio manager’s salary compensation is designed to be competitive with the marketplace and reflect a portfolio manager’s relative experience and contribution to the firm. Fixed base salary compensation is reviewed and adjusted annually to reflect increases in the cost of living and market rates.
Cryptocurrency is based on knowledge sharing on a distributed platform. The entire transactional history is for everyone to see. One blockchain is one thread of transaction. One unit or one block stores many transactions. The size of the block is 1MB and generally stores around 1000 to 2000 transactions. The data entered cannot be altered, nor can it be removed, enabling a system of complete transparency and trust. The entire money flow for the working model is beyond the traditional practices of controlling tax rates, credit usage, and money supply in the market.

Words of caution are appropriate when talking about going short and using leverage. These strategies are incredibly effective because they allow investors to not only profit from a general upward trend in bitcoin but to profit from the fluctuations in the market. At first, it is hard to think of a more perfect asset than bitcoin for such purposes. The upward trends have been fast and extreme, yet fluctuations are very common and tend to be substantial.
It can often be confusing to traders who are using multiple futures exchanges with different contract types -- inverse and qunato, dailies or quarterlies, 5x or 100x -- so people wonder: what should I trade? Well, it depends on what your goals are. If you are trying to do a little hedge for a medium term, you would want to use a quarterlies expiration contract instead, because otherwise you'd have to reopen shorter-term contracts after they expire and settle. 
application of the PFIC rules, certain excess distributions might have been classified as capital gains. In general, under the PFIC rules, an excess distribution is treated as having been realized ratably over the period during which the Fund held the PFIC shares. If a Fund receives an excess distribution with respect to PFIC stock, the Fund will itself be subject to tax on the portion of an excess distribution that is allocated to prior taxable years without the ability to reduce such tax by making distributions to Fund shareholders, and an interest factor will be added to the tax as if the tax had been payable in such prior taxable years.
The legal status of cryptocurrencies varies substantially from country to country and is still undefined or changing in many of them. While some countries have explicitly allowed their use and trade,[66] others have banned or restricted it. According to the Library of Congress, an "absolute ban" on trading or using cryptocurrencies applies in eight countries: Algeria, Bolivia, Egypt, Iraq, Morocco, Nepal, Pakistan, and the United Arab Emirates. An "implicit ban" applies in another 15 countries, which include Bahrain, Bangladesh, China, Colombia, the Dominican Republic, Indonesia, Iran, Kuwait, Lesotho, Lithuania, Macau, Oman, Qatar, Saudi Arabia and Taiwan.[67] In the United States and Canada, state and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating "bitcoin scams" and ICOs in 40 jurisdictions.[68]
If you want to do scalping, then shorter-term expiree contracts that settle really soon would be fine. Keep in mind, the normal state of futures markets is "contango", which means that longer dated contracts will have a premium to the current spot rate, to reflect the interest rate differential and time preference.  This means you will see Weeklies maybe with a $1-2 preium and Quarterlies (assuming they expire months from now) with a $5-8 premium.  As an example we have Quarterlies contracts right now at OKCoin that settle on December 25. So we're just starting December now, that means that even though these are "Quarterlies" contracts by classification, they are expiring not 3 months from now, but 1 month from now. Don't mix up the settlement expiration date with the naming convention. 
And this is where the BRR comes in. The BRR is the reference rate that is relevant for futures contracts and options in Bitcoin. When a futures contract or call option expires on a certain day, the owner will receive the difference between the BRR and the Bitcoin price in the contract as cash (if the BRR is higher than the price in the contract, of course). The BRTI, in contrast, is a real-time statistic that is not binding for any contracts; it tells you for what price you can currently (in this second) buy or sell Bitcoin on the markets.
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.

Each Fund may invest in money market instruments, which short-term cash instruments that have a remaining maturity of 397 days or less and exhibit high credit profiles, or cash or cash equivalents such as other high credit quality, short-term fixed income or similar securities, including (i) money market funds, (ii) U.S. Treasury Bills, which are U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government, and (iii) Repurchase Agreements, which are contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy them back at a specified time and price. Repurchase agreements are primarily used by the Funds as a short-term investment vehicle for cash positions.
The Board of Trustees of the Trust reserves the right to declare a split or a consolidation in the number of Shares outstanding of any Fund, and may make a corresponding change in the number of Shares constituting a Creation Unit, in the event that the per Share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.
Because a Fund invests in cash instruments denominated in foreign currencies, it may hold foreign currencies pending investment or conversion into U.S. dollars. Although the Fund values its assets daily in U.S. dollars, it does not convert its holdings of foreign currencies into U.S. dollars on a daily basis. The Fund will convert its holdings from time to time, however, and incur the costs of currency conversion. Foreign exchange dealers may realize a profit based on the difference between the prices at which they buy and sell various currencies. Thus, a dealer may offer to sell a foreign currency to the Fund at one rate, and offer to buy the currency at a lower rate if the Fund tries to resell the currency to the dealer.

The price of bitcoin may change sharply while the market for certain Bitcoin Instruments is closed or when the exchange on which Fund shares are traded is closed. Although the Funds will not invest directly in bitcoin, such price changes could impact the price and volatility of the Bitcoin Instruments in which the Funds invest and, therefore, could have a negative impact on your investment in the Funds.

Sections 1471-1474 of the Code and the U.S. Treasury and IRS guidance issued thereunder (collectively, “FATCA”) generally require a Fund to obtain information sufficient to identify the status of each of its shareholders under FATCA or under an applicable intergovernmental agreement (an “IGA”). If a shareholder fails to provide this information or otherwise fails to comply with FATCA or an IGA, a Fund or its agent may be required to withhold under FATCA at a rate of 30% with respect to that shareholder on ordinary dividends it pays to such shareholder and 30% of the gross proceeds of share redemptions or exchanges and certain Capital Gain Dividends it pays to such shareholder after December 31, 2018. If a payment by a Fund is subject to FATCA withholding, the Fund or its agent is required to withhold even if such payment would otherwise be exempt from withholding under the rules applicable to foreign shareholders described above (e.g., Capital Gain Dividends, short-term capital gain dividends, and interest-related dividends).

Equity/Index Swaps. In an equity swap, payments on one or both sides are linked to the performance of equities or an equity index. Equity swaps are normally used to (1) initiate and maintain long or short equity exposures either in an index or a specific stock portfolio; (2) temporarily eliminate exposure to an equity portfolio without disturbing the underlying equity position; or (3) increase, reduce, or eliminate market exposure to a single issue or a narrow stock portfolio or obtain greater diversification for a limited period of time without disturbing an underlying position.
  •   an officer of an investment company, or a person that would be an investment company but for the exclusions provided by sections 3(c)(1) and 3(c)(7) of the 1940 Act, having the same investment adviser or principal underwriter as the Trust or having an investment adviser or principal underwriter that directly or indirectly controls, is controlled by, or is under common control with the Advisor or principal underwriter of the Trust;
Each Fund has adopted certain investment restrictions as fundamental policies that cannot be changed without a “vote of a majority of the outstanding voting securities” of the Fund. The phrase “majority of outstanding voting securities” is defined in the 1940 Act as the lesser of: (i) 67% or more of the shares of the Fund present at a duly-called meeting of shareholders, if the holders of more than 50% of the outstanding shares of the Fund are present or represented by proxy; or (ii) more than 50% of the outstanding shares of the Fund. (All policies of a Fund not specifically identified in this Statement of Additional Information or its Prospectus as fundamental may be changed without a vote of the shareholders of the Fund.) For purposes of the following limitations, all percentage limitations apply immediately after a purchase or initial investment.
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.
