The term altcoin has various similar definitions. Stephanie Yang of The Wall Street Journal defined altcoins as "alternative digital currencies,"[25] while Paul Vigna, also of The Wall Street Journal, described altcoins as alternative versions of bitcoin.[26] Aaron Hankins of the MarketWatch refers to any cryptocurrencies other than bitcoin as altcoins.[27]
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 CFTC, in conjunction with other federal regulators, also recently proposed stricter margin requirements for certain swap transactions. If adopted, the proposed requirements could increase the amount of margin necessary to conduct many swap transactions, limit the types of assets that can be used as collateral for such transactions, and impose other restrictions. The rule proposal may affect the ability of the Funds to use swap agreements (as well as futures contracts and options on futures contracts or commodities) and may substantially increase regulatory compliance costs for the Advisor and the Funds. As of the date of this SAI, the ultimate impact of the rule proposal on the Funds is uncertain. It is possible, however, that any adopted rule may adversely affect the Advisor’s ability to manage the Funds, may impair a Funds’ ability to achieve its investment objective and/or may result in reduced returns to Fund investors.
The Bitcoin protocol was built using open source software by a small group of individuals who developed what is known today as “Bitcoin Core.” The open source nature of the Bitcoin protocol permits any developer to review the underlying code and suggest changes to it via “Bitcoin Improvement Proposals”, or “BIPs.” If accepted by a sufficient number of miners, BIPs may result in substantial changes to the Bitcoin Network, including changes that result in “forks” (as described herein). The Bitcoin Network has already experienced two major forks after developers attempted to increase transaction capacity. Blocks mined on these new “forked” networks now diverge from blocks mined on the original Bitcoin Network maintained by Bitcoin Core, resulting in the creation of two new blockchains whose digital assets are referred to as “bitcoin cash.” and “bitcoin gold.” Bitcoin, bitcoin cash and bitcoin gold now operate as separate, independent networks. Multiple BIPs still exist, many of which are aimed at increasing the transaction capacity of the Bitcoin Network, and it is possible that one or more of these BIPs could result in further network “forks.” Such changes may

Ripple is an open-source digital payment network, and it’s already being used by some of the world’s largest banks – such as the bank of Tokyo and Santandar. XRP has shown significant potential recently and has been turning a lot of heads. Ripple aims to become the go-to tool for banks on a global scale, while still giving an exciting investment opportunity to crypto advocates and solo investors. Ripple has many haters and I’ve been burned by it myself in the past – I sold 30,000 XRP at 20 cents… painful. Still, I did buy them at 3 cents a pop, so it could have been worse. I hold 10,000 XRP today and will hold until 2022.
The investment restrictions of the Funds specifically identified as fundamental policies may not be changed without the affirmative vote of at least a majority of the outstanding voting securities of that Fund, as defined in the 1940 Act. The investment objectives and all other investment policies of the Funds not specified as fundamental (including the index of a Fund) may be changed by the Board without the approval of shareholders.
Many expect bitcoin futures to stabilise the markets because big institutional investors will be able to trade bitcoin using all the flexibility present in sophisticated trading markets, with effective risk management and hedging strategies. Since the CME plans to set price limits on the trading range of bitcoin futures, the price of the coin is expected to become more stable. That is the optimistic outlook. It is reasonable to assume that if futures markets will indeed take off the way they are expected to, the market will eventually gravitate towards a less volatile state.
To purchase or redeem through the Clearing Process, an Authorized Participant must be a member of NSCC that is eligible to use the Continuous Net Settlement system. For purchase orders placed through the Clearing Process, the Authorized Participant Agreement authorizes the Distributor to transmit through the Funds’ transfer agent (the “Transfer Agent”) to NSCC, on behalf of an Authorized Participant, such trade instructions as are necessary to effect the Authorized Participant’s purchase order. Pursuant to such trade instructions to NSCC, the Authorized Participant agrees to deliver the requisite Deposit Securities and the Balancing Amount to the Trust, together with the Transaction Fee and such additional information as may be required by the Distributor.
Disclaimer: Trading carries a high level of risk, and may not be suitable for all investors. Before deciding to invest you should carefully consider your investment objectives, level of experience, and risk appetite. The possibility exists that you could sustain a loss of some or all of your initial investment and therefore you should not invest money that you cannot afford to lose. You should be aware of all the risks associated with foreign exchange trading, and seek advice from an independent financial advisor if you have any doubts.

On December 1, 2017, the CFTC issued a statement concerning the launch of bitcoin futures contracts on three CFTC-regulated futures exchanges – the CME, the CFE and the Cantor Exchange, cautioning that “market participants should take note that the relatively nascent underlying cash markets and exchanges for bitcoin remain largely unregulated markets over which the CFTC has limited statutory authority. There are concerns about the price volatility and trading practices of participants in these markets. We

  •   Ownership of bitcoin is pseudonymous and the supply of accessible bitcoins is unknown. There is no registry showing which individuals or entities own bitcoin or the quantity of bitcoin that is owned by any particular person or entity. It is possible, that a small group of early bitcoin adopters hold a significant proportion of the bitcoin that has been thus far created. There are no regulations in place that would prevent a large holder of bitcoin from selling its bitcoins, which could depress the price of bitcoin and have an adverse effect on an investment in the Fund.
To assist the Advisor in its responsibility for voting proxies and the overall proxy voting process, the Advisor has retained Institutional Shareholder Services (“ISS”) as an expert in the proxy voting and corporate governance area. ISS is a subsidiary of Vestar Capital Partners VI, L.P., a leading U.S. middle market private equity firm specializing in management buyouts and growth capital investments. The services provided by ISS include in-depth research, global issuer analysis and voting recommendations as well as vote execution, reporting and record keeping. ISS issues quarterly reports for the Advisor to review to assure proxies are being voted properly. The Advisor and ISS also perform spot checks intra-quarter to match the voting activity with available shareholder meeting information. ISS’s management meets on a regular basis to discuss its approach to new developments and amendments to existing policies. Information on such developments or amendments in turn is provided to the Proxy Committee. The Proxy Committee reviews and, as necessary, may amend periodically the Guidelines to address new or revised proxy voting policies or procedures.

It will not, though: Everyone is exhausted, so P&G will just add Peltz to its board. This makes sense. The election is for all practical purposes a tie; the difference in votes appears to be well within the margin for measurement error. I think in that scenario a tie has to go to the activist: If 49.98 percent of your shareholders think something is going wrong, you might as well do something to appease them. 

The Trust’s website has information about the premiums and discounts for each Fund. Premiums or discounts are the differences between the NAV and market price of a Fund on a given day, generally at the time NAV is calculated. A premium is the amount that a Fund is trading above the NAV. A discount is the amount that the Fund is trading below the NAV.

Distributions of Shares shall be made to DTC or its nominee, Cede & Co., as the registered holder of all Shares. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in Shares as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial owners of Shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants. The Trust has no responsibility or liability for any aspects of the records relating to or notices to Beneficial owners, or payments made on account of beneficial ownership interests in such Shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial owners owning through such DTC Participants.

Don’t FOMO. This is a spot that people most frequently lose money on. A dash of manipulation, two tablespoons of media hype, a cup of CME and CBOE announcements, and a generous handful of FOMO drove Bitcoin prices from $10,000 to $20,000 in December. Since that time, Bitcoin fell to a low of $9,000 and is currently sitting at around $11,000. It’s easy to look back and say, “if only I waited one month, then I could’ve bought at $9,000 instead of waiting for Bitcoin to hit $20,000 again for me to break even.” But the reality is, the combination of 1) being greedy, 2) investing blindly, and 3) FOMO were likely large contributors to the purchase at an all-time-high. Even in the crazy world of cryptocurrency, if a coin pumps that quickly, it will correct — it’s a matter of time. Speculative pumps are almost always followed by dips. While trying to jump onto a train going full speed sounds like something straight out of a James Bond movie, I’m sure most of us can agree we would probably save some limbs if we just waited for it at the next stop.
The Advisor’s proxy voting policies and procedures (the “Guidelines”) are reasonably designed to maximize shareholder value and protect shareowner interests when voting proxies. The Advisor’s Brokerage Allocation and Proxy Voting Committee (the “Committee”) exercises and documents the Advisor’s responsibilities with regard to voting of client proxies. The Committee is composed of employees of the Advisor. The Proxy Committee reviews and monitors the effectiveness of the Guidelines.
Shareholders that are U.S. persons and own, directly or indirectly, more than 50% of a Fund could be required to report annually their “financial interest” in the Fund’s “foreign financial accounts,” if any, on FinCEN Form 114, Report of Foreign Bank and Financial Accounts (“FBAR”). Shareholders should consult a tax advisor, and persons investing in a Fund through an intermediary should contact their intermediary, regarding the applicability to them of this reporting requirement.
These are fundraising mechanisms for newly launched cryptocurrencies. Investors in ICOs receive tokens in the new venture. Investors have poured billions of dollars into more than 1,000 ICOs over the past year. While many ICOs are legitimate, the vast majority have no real business plans or technology behind them. Many get launched with nothing more than a whitepaper by individuals with no technology or industry experience.

The CME Group contract (symbol "BTC") began trading on December 18, 2017, building off of the success of the BRR and demand for a regulated trading venue for the digital asset market. The contract is cash-settled, based on the CME CF Bitcoin Reference Rate (BRR) which serves as a once-a-day reference rate of the U.S. dollar price of bitcoin. Bitcoin futures are listed on and subject to the rules of CME.2
•   Counterparty Risk —The Fund bears the risk that the counterparty to derivative transaction, such as a futures contract, defaults or otherwise fails to honor its obligations. If a counterparty defaults, the Fund will lose money and the value of an investment in the Fund may decrease. The Fund may engage in futures transactions with a limited number of counterparties, which may increase the Fund’s exposure to counterparty risk. The effect of the volatility of bitcoin pricing or other aspects of trading in bitcoin futures on futures clearinghouses for bitcoin futures is currently unknown, and may result in increased counterparty risk.
reporting systems. As of October 2016, the Advisor has separate arrangements to make payments, other than for the educational programs and marketing activities described above, to Charles Schwab & Co., Inc. and Raymond James Financial Services, Inc. (the “Firms”). Pursuant to the arrangements with the Firms, the Firms agreed to promote certain ProShares ETFs to each Firm’s customers and not to charge certain of their customers any commissions when those customers purchase or sell shares of certain ProShares ETFs. These payments, which may be significant, are paid by the Advisor from its own resources and not from the assets of the Funds. A discussion regarding the basis for the Board of Trustees approving the Advisory Agreement of the Trust will be (or is) available in the Trust’s Annual and/or Semi-Annual Report to shareholders. The Investment Advisory fees paid, as well as any amounts reimbursed pursuant to the Expense Limitation Agreement, for the fiscal years ended May 31, 2015, May 31, 2016 and May 31, 2017 for each Fund that was operational as of each date are set forth below. Because each of the New Funds was not operational at the end of the Trust’s last fiscal year, information on investment advisory fees paid by the Fund is not included in this SAI.

This mega-powerful currency has not only opened the gate for other currencies, but also leads the cryptocurrency world with pride. It is governed to make sure no extra Bitcoin is produced, as a maximum quantity of 21 Million Bitcoin units was agreed to. When introduced, the rate was $1 to 1,309 BTC. The wheel has turned, and when Bitcoin reached the all-time high of $19,783.21 in 2017, it was certainly a meaningful milestone for Satoshi Nakamoto, the creator of Bitcoin.

Paul Krugman, Nobel Memorial Prize in Economic Sciences winner does not like bitcoin, has repeated numerous times that it is a bubble that will not last[110] and links it to Tulip mania.[111] American business magnate Warren Buffett thinks that cryptocurrency will come to a bad ending.[112] In October 2017, BlackRock CEO Laurence D. Fink called bitcoin an 'index of money laundering'.[113] "Bitcoin just shows you how much demand for money laundering there is in the world," he said.
The Administrator pays all fees and expenses that are directly related to the services provided by the Administrator to the Funds; each Fund reimburses the Administrator for all fees and expenses incurred by the Administrator which are not directly related to the services the Administrator provides to the Funds under the service agreement. Each Fund may also reimburse the Administrator for such out-of-pocket expenses as incurred by the Administrator in the performance of its duties. For these services each Fund that was operational for the period indicated paid the Administrator and Citi the amounts set forth below. Because the New Fund was not operational at the end of the Trust’s last fiscal year, information on fees paid to the Administrator and Citi on behalf of the New Fund is not included in this SAI.

impede the functionality of the Bitcoin Network and adversely affect the price of bitcoin. Any technical disruptions or regulatory limitations that affect Internet access may have an adverse effect on the Bitcoin Network, the price of bitcoin and the bitcoin futures contracts in which the Fund invests. In addition to technical disruptions such as cyber-attacks, the potential elimination of the net neutrality regulations in the U.S. may have a negative impact on bitcoin and the Bitcoin ecosystem.
The promoters of these products promise traders a way to beat the market by arbitraging prices between different exchanges. Don’t believe the hype. Bitcoin exchanges often have expensive withdrawal processes and hefty fees for trading bitcoin with fiat currencies, such as dollars or euros. Also, settlement of bitcoin trades can take hours. These factors will eliminate any profits from bitcoin arbitrage and may even lead to losses.
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.
You could imagine the spread going the other way, though. If everyone really was clamoring to short bitcoin, and if the futures offered a more convenient way to do it than the bitcoin exchanges, then you'd expect the short sellers to pay a premium to short via futures. Instead of selling a bitcoin at $18,000 today, they'd be willing to sell a synthetic bitcoin for $17,500, paying the spread to an arbitrageur who was willing to do the actual shorting for them. But the fact that the spread is mostly positive, and that bitcoin's price has been mostly going up, suggests that the demand has mostly been for synthetic long positions, not short.
participating in a distribution (as opposed to engaging in ordinary secondary market transactions), and thus dealing with the Fund’s shares as part of an “unsold allotment” within the meaning of Section 4(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the Securities Act.
Some Funds focus their investments in particular foreign geographical regions or countries. In addition to the risks of investing in foreign securities discussed above, the investments of such Funds may be exposed to special risks that are specific to the country or region in which the investments are focused. Furthermore, Funds with such a focus may be subject to additional risks associated with events in nearby countries or regions or those of a country’s principal trading partners. Additionally, some Funds have an investment focus in a foreign country or region that is an emerging market and, therefore, are subject to heightened risks relative to Funds that focus their investments in more developed countries or regions.

Make loans to other persons, except that the acquisition of bonds, debentures or other corporate debt securities and investment in government obligations, commercial paper, pass-through instruments, certificates of deposit, bankers’ acceptances and repurchase agreements and purchase and sale contracts and any similar instruments shall not be deemed to be the making of a loan, and except, further, that the Fund may lend its portfolio securities, provided that the lending of portfolio securities may be made only in accordance with applicable law and the guidelines set forth in the Prospectus and this SAI, as they may be amended from time to time.
The Advisor, with the assistance of ISS, maintains for a period of at least five years a record of each proxy statement received and materials that were considered when the proxy was voted during the calendar year. Information on how the Funds voted proxies relating to portfolio securities for the 12-month (or shorter) period ended June 30 is available without charge, upon request, (1) by calling the Advisor at 888-776-3637, (2) on the Trust’s website at, and (3) on the SEC’s website at

•   A Fund’s income from or the proceeds of dispositions of its non-U.S. investments may be subject to withholding and other taxes imposed by foreign countries, which will reduce the Fund’s return on and taxable distributions in respect of its non-U.S. investments. Tax conventions between certain countries and the United States may reduce or eliminate these taxes. If more than 50% of the value of a Fund’s total assets at the close of a taxable year consists of securities of foreign corporations, the Fund will be eligible to elect to “pass through” to you foreign income taxes that it has paid. If this election is made, you will be required to include your share of those taxes in gross income as a distribution from the Fund and you generally will be allowed to claim a credit (or a deduction, if you itemize deductions) for these amounts on your federal U.S. income tax return, subject to certain limitations.
Market Spotlight – Bitcoin - A cryptocurrency is a digital asset designed to work as a medium of exchange using cryptography to secure transactions, control creation, and verify transactions. The first such cryptocurrency, Bitcoin, was introduced in 2009. In 2017, the exchanges launched a Bitcoin futures contract. The CBOE contract launched on Sunday, December 10, while the CME contract launched on Monday, December 18.
Several factors may affect a Fund’s ability to achieve a high degree of correlation with its benchmark. Among these factors are: (i) a Fund’s fees and expenses, including brokerage (which may be increased by high portfolio turnover) and the costs associated with the use of derivatives; (ii) less than all of the securities underlying a Fund’s benchmark being held by the Fund and/or securities not included in its benchmark being held by a Fund; (iii) an imperfect correlation between the performance of instruments held by a Fund, such as futures contracts, and the performance of the underlying securities in a benchmark; (iv) bid-ask spreads (the effect of which may be increased by portfolio turnover); (v) holding instruments traded in a market that has become illiquid or disrupted; (vi) a Fund’s share prices being rounded to the nearest cent; (vii) changes to the benchmark that are not disseminated in advance; (viii) the need to conform a Fund’s portfolio holdings to comply with investment restrictions or policies or regulatory or tax law requirements;
“Qualified dividend income” received by an individual is taxed at the rates applicable to net capital gain. In order for some portion of the dividends received by a Fund shareholder to be qualified dividend income, the Fund must meet holding period and other requirements with respect to some portion of the dividend-paying stocks in its portfolio and the shareholder must meet holding period and other requirements with respect to the Fund’s Shares. A dividend will not be treated as qualified dividend income (at either the Fund or shareholder level) (1) if the dividend is received with respect to any share of stock held for fewer than 61 days during the 121-day period beginning on the date which is 60 days before the date on which such share becomes ex-dividend with respect to such dividend (or, in the case of certain preferred stock, 91 days during the 181-day period beginning 90 days before such date), (2) to the extent that the recipient is under an obligation (whether pursuant to a short sale or otherwise) to make related payments with respect to positions in substantially similar or related property, (3) if the recipient elects to have the dividend income treated as investment income for purposes of the limitation on deductibility of investment interest, or (4) if the dividend is received from a foreign corporation that is (a) not eligible for the benefits of a comprehensive income tax treaty with the United States (with the exception of dividends paid on stock of such a foreign corporation that is readily tradable on an established securities market in the United States) or (b) treated as a passive foreign investment company. In general, distributions of investment income reported by a Fund as derived from qualified dividend income will be treated as qualified dividend income in the hands of a shareholder taxed as an individual, provided the shareholder meets the holding period and other requirements described above with respect to the Fund’s Shares.
A distribution will be treated as paid on December 31 of a calendar year if it is declared by a Fund in October, November or December of that year with a record date in such a month and is paid by the Fund during January of the following year. Such distributions will be taxable to shareholders in the calendar year in which the distributions are declared, rather than the calendar year in which the distributions are received.
The Fund may invest in stocks of large-cap companies. Although returns on investments in large-cap companies are often perceived as being less volatile than the returns of companies with smaller market capitalizations, the return on large-cap securities could trail the returns on investments in smaller and mid-sized companies for a number of reasons. For example, large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies.
Look, you and I are sophisticated, and we get that "bitcoin's price increase is deflationary and makes it a bad currency" is not a good argument against bitcoin, because "bitcoin is a bad currency" is not a good argument against bitcoin. (People keep making it though.) Bitcoin's value proposition -- much like that of gold -- is that it is an uncorrelated store of value, not that it is useful for buying a sandwich. But at the same time you have to watch out for business models that are based on the casual assumption that bitcoin works just like a currency. "Cryptocurrency-financed warehouse lending" has the word "cryptocurrency" in it, so it's worth billions of dollars, but I'm not sure it works as a business model.
  (c) A “Disinterested Trustee” is one (i) who is not an Interested Person of the Trust (including anyone, as such Disinterested Trustees, who has been exempted from being an Interested Person by any rule, regulation or order of the Commission), and (ii) against whom none of such actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending;
A large investor tends to have portfolios that are diversified enough that they can stomach deviations from expected price movements even with leverage. But smaller investors have smaller accounts, and that is where leverage can be fatal. This is because amplified losses can grow larger than the account balance and cause the need for a margin call when facing the prospect of going into severe debt.
On September 17, 2015, the CFTC provided clarity regarding the regulatory treatment of bitcoin in the Coinflip civil enforcement case. There the CFTC determined that bitcoin and other virtual currencies are regulated as commodities under the CEA. Based on this determination, the CFTC applied CEA provisions and CFTC regulations that apply to a bitcoin derivatives trading platform. Also of significance, the CFTC took the position that bitcoin is not encompassed by the definition of currency under the CEA and CFTC regulations. The CFTC defined bitcoin and other “virtual currencies” as “a digital representation of value that functions as a medium of exchange, a unit of account, and/or a store of value, but does not have legal tender status in any jurisdiction. Bitcoin and other virtual currencies are distinct from ‘real’ currencies, which are the coin and paper money of the United States or another country that are designated as legal tender, circulate, and are customarily used and accepted as a medium of exchange in the country of issuance.” On July 6, 2017, the CFTC granted LedgerX, LLC an order of registration as a Swap Execution Facility for digital assets and on July 24, 2017, the CFTC approved Ledger X, LLC as the first derivatives clearing organization for digital currency. On September 21, 2017, the CFTC filed a civil enforcement action in federal court against a New York corporation and its principal, charging them with fraud, misappropriation, and issuing false account statements in connection with a Ponzi scheme involving investments in bitcoin, which the CFTC asserted is a commodity subject to its jurisdiction.

•	 	Valuation Risk — In certain circumstances, portfolio holdings may be valued using techniques other than market quotations. The value established for a portfolio holding may be different from what would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio holding that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio holding for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio holding is sold at a discount to its established value.

A Bitcoin futures contract is exactly what you would expect from the example above, replacing pork bellies with Bitcoin. It is a contract that enables you to buy Bitcoin at a predetermined price at a specific point in the future. For example, if today’s Bitcoin price is 8,000 USD per BTC and you expect it to rise to 10,000 USD per BTC in 4 weeks, then entering a contract which allows you to buy Bitcoin at 9,000 USD in 4 weeks is highly attractive.
