In a possible lead-up to its plans on becoming an ATS, on March 26, 2018, San Francisco-based Coinbase announced it was adding support for ERC20 into all its trading platforms. ERC20 is the Ethereum technical standard that the majority of ICO tokens are based on. “This paves the way for supporting ERC20 assets across Coinbase products in the future, though we aren’t announcing support for any specific assets or features at this time,” Coinbase said in a blog post.
A U.S. person, including a Fund, who owns (directly or indirectly) 10% or more of the total combined voting power of all classes of stock of a foreign corporation is a “U.S. Shareholder” for purposes of the CFC provisions of the Code. A CFC is a foreign corporation that, on any day of its taxable year, is owned (directly, indirectly, or constructively) more than 50% (measured by voting power or value) by U.S. Shareholders. Because of its investment in its Subsidiary, each Parent Fund is a U.S. Shareholder in a CFC. As a U.S. Shareholder, each Parent Fund is required to include in gross income for U.S. federal income tax purposes for each taxable year of the Fund its pro rata share of its CFC’s “subpart F income” for the CFC’s taxable year ending within the Fund’s taxable year whether or not such income is actually distributed by the CFC, provided that the foreign corporation has been a CFC for at least 30 uninterrupted days in its taxable year. Subpart F income generally includes interest, OID, dividends, net gains from the disposition of stocks or securities, net gains from transactions (including futures, forward, and similar transactions) in commodities, receipts with respect to securities loans, and net payments received with respect to equity swaps and similar derivatives. Subpart F income is treated as ordinary income, regardless of the character of the CFC’s underlying income. Net losses incurred by a CFC during a tax year do not flow through to an investing Fund and thus will not be available to offset income or capital gain generated from that Fund’s other investments. In addition, net losses incurred by a CFC during a tax year generally cannot be carried forward by the CFC to offset gains realized by it in subsequent taxable years. To the extent each Parent Fund invests in its Subsidiary and recognizes subpart F income in excess of actual cash distributions from such the Subsidiary, if any, it may be required to sell assets (including when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level. Subpart F income also includes the excess of gains over losses from transactions (including futures, forward and other similar transactions) in commodities.
A piece of software or hardware that gives you the ability to store and exchange your cryptocurrencies. Each cryptocurrency wallet is encrypted and unique. When you send funds you actually broadcast an encrypted message to the recipient. Only the recipient’s cryptocurrency wallet can decrypt that message and thus receive the funds. A hardware cryptocurrency wallet is considered to have key advantages over other software wallets:
  •   A decline in the adoption of bitcoin could have a negative effect on the price of bitcoin and bitcoin-related investments. Bitcoin’s adoption has been on a generally continuous climb since bitcoin first gained mass media attention in 2013. However, there can be no guarantees this growth will continue. Further, adoption of bitcoin as a means of payment has been limited when compared with the increase in the price of bitcoin, indicating that the majority of bitcoin’s use is for investment and speculative purposes. A lack of acceptance of bitcoin as a means of payment could negatively impact the price of the bitcoin futures contracts in which the Fund invests.
Each Fund may consider changing its index at any time, including if, for example: the current index becomes unavailable; the Board believes that the current index no longer serves the investment needs of a majority of shareholders or that another index may better serve their needs; or the financial or economic environment makes it difficult for the Fund’s investment results to correspond sufficiently to its current index. If believed appropriate, a Fund may specify an index for itself that is “leveraged” or proprietary. There can be no assurance that a Fund will achieve its objective.

In September 2015, the establishment of the peer-reviewed academic journal Ledger (ISSN 2379-5980) was announced. It covers studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh.[114][115] The journal encourages authors to digitally sign a file hash of submitted papers, which will then be timestamped into the bitcoin blockchain. Authors are also asked to include a personal bitcoin address in the first page of their papers.[116][117]

For hedging purposes, the Funds may invest in forward currency contracts to hedge either specific transactions (transaction hedging) or portfolio positions (position hedging). Transaction hedging is the purchase or sale of forward currency contracts with respect to specific receivables or payables of the Funds in connection with the purchase and sale of portfolio securities. Position hedging is the sale of a forward currency contract on a particular currency with respect to portfolio positions denominated or quoted in that currency.
In pure financial theory, the value of a futures contract is based on a "no arbitrage condition" from the interest rates in each asset. We have Bitcoin and US Dollar. Bitcoin interest rates tend to be less than US Dollar interest rates, so when you want to replicate the future value of bitcoin in US dollars, you have to borrow USD at, say, 5%, and invest in Bitcoin at 1% return. This requires a premium on the futures exchange to be able to hedge that trade. 
Interest Rate Risk — The Fund intends to invest a substantial portion of its assets in U.S. Treasury securities and is subject to interest rate risk. Interest rate risk is the risk that debt securities may fluctuate in value due to changes in interest rates. Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. The value of securities with longer maturities may fluctuate more in response to interest rate changes than securities with shorter maturities. A wide variety of factors can cause interest rates to rise (e.g., central bank monetary
•   Active Management Risk — The performance of actively managed funds reflects, in part, the ability of ProShare Advisors to select investments and make investment decisions that are suited to achieving the Fund’s investment objective. ProShare Advisors’ judgments about the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by ProShare Advisors fail to produce the intended results, the Fund may not achieve its investment objective and could underperform other funds with a similar investment objective and/or strategies. The Fund does not seek to provide investment performance that would be opposite of a 30% investment in bitcoin futures contracts and a 70% investment in U.S. government securities.
The Board oversight of the Trust and the Funds extends to the Trust’s risk management processes. The Board and its Audit Committee consider risk management issues as part of their responsibilities throughout the year at regular and special meetings. The Advisor and other service providers prepare regular reports for Board and Audit Committee meetings that address a variety of risk-related matters, and the Board as a whole or the Audit Committee may also receive special written reports or presentations on a variety of risk issues at the request of the Board or the Audit Committee. For example, the portfolio managers of the Funds meet regularly with the Board to discuss portfolio performance, including investment risk, counterparty risk and the impact on the Funds of investments in particular securities or derivatives. As noted above, given the relatively small size of the Board, the Board determined it is not necessary to adopt a complex leadership structure in order for the Board to effectively exercise its risk oversight function.
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.

•   Equity and Market Risk — The equity markets are volatile, and the value of securities, swaps, futures, and other instruments correlated with the equity markets may fluctuate dramatically from day-to-day. Equity markets are subject to corporate, political, regulatory, market and economic developments, as well as developments that impact specific economic sectors, industries or segments of the market. Further, stocks may underperform other equity investments. Volatility in the markets and/or market developments may cause the value of an investment in the Fund to decrease.


As of February 2018, the Chinese Government halted trading of virtual currency, banned initial coin offerings and shut down mining. Some Chinese miners have since relocated to Canada.[43] One company is operating data centers for mining operations at Canadian oil and gas field sites, due to low gas prices.[44] In June 2018, Hydro Quebec proposed to the provincial government to allocate 500 MW to crypto companies for mining.[45] According to a February 2018 report from Fortune,[46] Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity. Prices are contained because nearly all of the country’s energy comes from renewable sources, prompting more mining companies to consider opening operations in Iceland. The region’s energy company says bitcoin mining is becoming so popular that the country will likely use more electricity to mine coins than power homes in 2018. In October 2018 Russia will become home to one of the largest legal mining operations in the world, located in Siberia. More than 1.5 million Russians are engaged in home mining. Russia’s energy resources and climate provide some of the best conditions for crypto mining.[47]
Bitcoin is a relatively new type of currency—a digital or cryptocurrency secured through cryptography, or codes that can’t be read without a key. Traditional currencies are made up of paper bills and coins. Unlike traditional currencies, the bitcoin is not issued by any central government. Rather, a computer algorithm determines how many bitcoins are produced and added to the economy. This is much different than a traditional currency, where central banks typically determine how much money to print.
  •   The bitcoin exchanges on which bitcoin trades are relatively new and, in most cases, largely unregulated and, therefore, may be more exposed to volatility, fraud and security breaches than established, regulated exchanges for other products. Over the past several years, a number of Bitcoin Exchanges have been closed due to fraud, failure, security breaches or governmental regulations. The nature of the assets held at Bitcoin Exchanges make them appealing targets for hackers and a number of Bitcoin Exchanges have been victims of cybercrimes. No Bitcoin Exchange is immune from these risks. Fraudulent activity can increase volatility and have an adverse effect on the price of bitcoin, the general acceptance of bitcoin as an investment or means of currency and could have a negative impact on the bitcoin futures contracts in which the Fund invests and the value of the Fund.
Moody’s ratings for state and municipal notes and other short-term loans are designated Moody’s Investment Grade (MIG) and for variable rate demand obligations are designated Variable Moody’s Investment Grade (VMIG). This distinction recognizes the differences between short-term credit risk and long-term risk. Loans bearing the designation MIG-1/VMIG-1 are of the best quality, enjoying strong protection from established cash flows of funds for their servicing or from established and broad-based access to the market for refinancing, or both. Loans bearing/with the designation MIG-2/VMIG-2 are of high quality, with ample margins of protection, although not as large as the preceding group.
So far, these derivatives market have only been a niche occupied by crypto enthusiasts. That is until one of the newcomers, Crypto Facilities, and an incumbent in the derivatives market have joined forces: Crypto Facilities and the CME Group. The CME Group (controlling, for example, the Chicago Mercantile Exchange that has been around for more than a century) is a large-scale business that is officially regulated and audited by the US financial authorities. It settles its contracts in fiat money rather than cryptocurrency, thus enabling non-crypto experts to speculate on Bitcoin.
