•   The Code generally imposes a 3.8% Medicare contribution tax on the “net investment income” of certain individuals, trusts and estates to the extent their income exceeds certain threshold amounts. For these purposes, “net investment income” generally includes, among other things, (i) distributions paid by a Fund of ordinary dividends and capital gain dividends, and (ii) any net gain from the sale, redemption or exchange of Fund shares. Shareholders are advised to consult their tax advisors regarding the possible implications of this additional tax on their investment in a Fund.
Each Fund bears all expenses of its operations other than those assumed by ProShare Advisors or the Administrator. Fund expenses include but are not limited to: the investment advisory fee; management services fee; administrative fees, index receipt agent fees, principal financial officer/treasurer services fees; compliance service fees, anti-money laundering administration fees; custodian and accounting fees and expenses, legal and auditing fees; securities valuation expenses; fidelity bonds and other insurance premiums; expenses of preparing and printing prospectuses, proxy statements, and shareholder reports and notices; registration fees and expenses; proxy and annual meeting expenses, if any; licensing fees; listing fees; all federal, state, and local taxes (including, without limitation, stamp, excise, income, and franchise taxes); organizational costs; and Independent Trustees’ fees and expenses.
Altcoins is the general term associated with the cryptocurrencies launched after Bitcoin’s success. At first, these were mere copies mimicking the original Bitcoin. Today, there are over 1,000 of these, and the list just keeps growing. Most crypto coins are launched following an ICO (Initial Coin Offering – a form of crowdfunding) in which the developers raise cash by offering a limited number of initial coins to finance technological development. So far, besides the list below, we can find names, such as Namecoin, Peercoin, Bytecoin, Deutsche eMark, Novacoin, Cryptogenic Bullion, Quark, DarkCoin and Mangocoinz (for smartphones).
Special Note Regarding the Correlation Risks of Geared Funds (All Funds, except the Matching ProShares Funds, the Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF and the CDS Short North American HY Credit ETF)
These days, all of the BTC/USD contracts trading at active futures markets are inverse, as mentioned in the beginning of this guide. The only differences between the exchanges is how they trigger liquidations and the procedure for handling margin calls. They all use Bitcoin as the currency, of course, and you can use the table below for a basic feature comparison:

Under normal market conditions, each Fund intends to invest substantially all of its assets in Benchmark Futures Contracts. The contractual obligations of a buyer or seller holding a futures contract to expiration may be satisfied by settling in cash as designated in the contract specifications. Alternatively, futures contracts may be closed out prior to expiration by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of settlement. Once this date is reached, the futures contract “expires.” The Funds do not intend to hold bitcoin futures contracts through expiration, but instead to “roll” their respective positions. “Rolling” refers to a process whereby futures contracts nearing expiration are closed out and replaced with an identical futures contract with a later expiration date. Accordingly, the Funds are subjects to risks related to rolling.
Note that any losses on the bitcoin position is offset by the short position in the Jan XBT Futures contract.  Because Jan XBT was trading at a $1,000 premium to spot bitcoin, the profit for this trade is equal to that difference.  Now, keep in mind if bitcoin doubles between now and January 17 settlement the maximum profit is $1000.  Larry is giving up some upside to assure a return of $1000.
  •   Changes in the Bitcoin Network could have an adverse effect on the operation and value of bitcoin, which could have an adverse effect on the value of Bitcoin Futures Contracts and the value of Fund Shares. 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.” Such changes may influence the price of Bitcoin and Bitcoin Futures Contracts. In particular, it is possible that the price of the Bitcoin Futures Contracts subsequent to a “fork” may be linked to the price of bitcoin on only one of the resulting Bitcoin Networks, rather than the aggregate price of bitcoin on all resulting Bitcoin Networks. The CBOE Futures Exchange (“CFE”) and Chicago Mercantile Exchange (“CME”) have announced different protocols for addressing forks.
What’s important to consider as crypto evolves is to learn everything (or as much as possible) for yourself. Crypto coins all offer white papers to the public (though they’re not always easy to find). They’re for a scientific audience, but you’ve probably read worse if you have a university degree. Find them and read them. Don’t understand something, ask a question.

 	•	 	Intellectual property rights claims may adversely affect the operation of the Bitcoin Network. Third parties may assert intellectual property rights claims relating to the operation of the Bitcoin Network. Regardless of the merit of any intellectual property or other legal action, any threatened action that reduces confidence in the Bitcoin Network’s long-term viability or the ability of end-users to hold and transfer bitcoin may adversely affect the price of bitcoin and adversely affect the price of the Bitcoin Futures Contracts held by the Fund.

The Funds are exchange-traded funds (“ETFs”) and the shares of each Fund (“Shares”) are listed on NYSE Arca, The NASDAQ Stock Market or the Bats BZX Exchange, Inc., (each, an “Exchange”). The Shares trade on the relevant Exchange at market prices that may differ to some degree from the Shares’ NAVs. Each Fund issues and redeems Shares on a continuous basis at NAV in large, specified numbers of Shares called “Creation Units.” Creation Units of the Funds are issued and redeemed in-kind for securities and an amount of cash or entirely in cash, in each case at the discretion of ProShare Advisors LLC (the “Advisor” or “ProShare Advisors”). Except when aggregated in Creation Units, Shares cannot be purchased from and are not redeemable securities of the Funds. Retail investors, therefore, generally will not be able to purchase or redeem the Shares directly. Rather, most retail investors will purchase and sell Shares in the secondary market with the assistance of a broker. Reference is made to the Prospectus for a discussion of the investment objectives and policies of each of the Funds. The discussion below supplements, and should be read in conjunction with, the Prospectus. Portfolio management is provided to the Funds by ProShare Advisors, a Maryland limited liability company with offices at 7501 Wisconsin Avenue, Suite 1000E, Bethesda, MD 20814.
Unsponsored ADR programs are organized independently and without the cooperation of the issuer of the underlying securities. As a result, available information concerning the issuers may not be as current for unsponsored ADRs, and the price of unsponsored depositary receipts may be more volatile than if such instruments were sponsored by the issuer and/or there may be no correlation between available information and the market value.
Shares will be continuously offered for sale by the Trust through the Distributor only in Creation Units, as described below under “Purchase and Issuance of Creation Units.” Shares in less than Creation Units are not distributed by the Distributor. The Distributor also acts as agent for the Trust. The Distributor will deliver a Prospectus to persons purchasing Shares in Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the 1934 Act and a member of the Financial Industry Regulatory Authority, Inc. The Distributor has no role in determining the investment policies of the Funds or which securities are to be purchased or sold by the Funds.
ProShares Crude Oil Strategy ETF is an actively managed fund that seeks to provide total return through actively managed exposure to the West Texas Intermediate (“WTI”) crude oil futures markets. The Fund’s strategy seeks to outperform certain index based strategies by actively managing the rolling of WTI crude oil futures contracts. “Rolling” means selling a futures contract as it nears its expiration date and replacing it with a new futures contract that has a later expiration date. The Fund generally selects between WTI crude oil futures contracts with the three nearest expiration dates (known as the front, second and third month contracts) based on ProShare Advisors’ analysis of the liquidity and cost of establishing and maintaining such positions. Each month, the Fund will evaluate this strategy on or about the fifth business day of the month and may roll its position from the fifth through ninth business days into the contract month determined by the Fund’s active investment strategy.
Ziddu Coin is a smart contract that enables SME’s, processors, manufacturers, importers and exporters using cryptocurrencies across continents. Ziddu Coins are loosely pegged to Ethereum and Bitcoin. The importers/exporters convert offered Ziddu coins into Ethereum or Bitcoin and use the proceeds for their working capital needs. At the end of the contract, importers/exporters will realize their proceeds and pay back their funds through cryptocurrencies only. Depending upon the risk profile of the counterparty, the interest will vary from 12% to 48%.
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 www.ProShares.com, and (3) on the SEC’s website at http://www.sec.gov.

Futures markets create an immense amount of flexibility. They enable investors to readily bet on an asset or bet against it (go long or go short), and they are usually characterised by an immense amount of leverage. In the case of bitcoin, this means one can trade a high volume of coins while only paying for a fraction of them, essentially operating with borrowed money. Leverage is used to amplify profits on a small volume of assets, but it is a double-edged sword in that it also amplifies losses.

Caspian offers an institutional-grade system that allows traders to avoid this barrier and seamlessly connect to multiple exchanges.

Caspian plans to add up to 40 additional trading platforms by Q3 of this year.

A cryptocurrency is a digital coin, designed to be transferred between people in virtual transactions. Cryptocurrencies exist only as data and not as physical objects; you cannot actually hold a Bitcoin in your hand or keep Ethereum in your safe. Owning a Bitcoin means you have the collective agreement of each and every computer on the Bitcoin network that it is currently owned by you and – more importantly – that it was legitimately created by a miner.
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).
Cboe Futures Exchange, LLC (CFE) launched trading in Cboe bitcoin futures at 5:00 p.m. Central Time on December 10 under the ticker symbol “XBT”. XBT℠ futures are cash-settled contracts based on the Gemini’s auction price for bitcoin, denominated in U.S. dollars. Gemini Trust Company, LLC (Gemini) is a digital asset exchange and custodian founded in 2014 that allows customers to buy, sell, and store digital assets such as bitcoin, and is subject to fiduciary obligations, capital reserve requirements, and banking compliance standards of the New York State Department of Financial Services.3
In traditional financial markets, derivatives are used as speculation objects as well as insurance against losses. The latter is known as hedging. One popular variety of derivatives used for hedging are called futures. A future is a contract between two parties in which one party agrees to pay the other a predetermined amount of money for an underlying asset at a specific point in time.
