•   Lack of liquid markets, and possible manipulation of blockchain-based assets. Digital assets that are represented and trade on a blockchain may not necessarily benefit from viable trading markets. Stock exchanges have listing requirements and vet issuers, and perhaps users. These conditions may not necessarily be replicated on a blockchain, depending on the platform’s controls and other policies. The more lenient a blockchain is about vetting issuers of digital assets or users that transact on the platform, the higher the potential risk for fraud or the manipulation of digital assets. These factors may decrease liquidity or volume, or increase volatility of digital securities or other assets trading on a blockchain.
From time to time, proxy issues may pose a material conflict of interest between Fund shareholders and the Advisor, the Distributor or any affiliates thereof. Due to the limited nature of the Advisor’s activities (e.g., no underwriting business, no publicly traded affiliates, no investment banking activities and no research recommendations), conflicts of interest are likely to be infrequent. Nevertheless, it shall be the duty of the Committee to monitor potential conflicts of interest. In the event a conflict of interest arises, the Advisor will direct ISS to use its independent judgment to vote affected proxies in accordance with approved guidelines. The Committee will disclose to the Board of Trustees the voting issues that created the conflict of interest and the manner in which voted such proxies were voted.
Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[30] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[1] This difficulty is derived from leveraging cryptographic technologies.
Pursuant to an investment advisory and management agreement between ProShare Advisors and the Trust on behalf of each Unitary Fee Fund, each Unitary Fee Fund pays ProShare Advisors a fee at an annualized rate based on its average daily net assets as follows: 0.27% for S&P 500 Ex-Energy ETF; 0.27% for S&P 500 Ex-Financials ETF; 0.27% for S&P 500 Ex-Health Care ETF; 0.27% for S&P 500 Ex-Technology ETF; 0.35% for Equities for Rising Rates ETF; 0.30% for Investment Grade—Interest Rate Hedged; 0.35% for S&P 500 Dividend Aristocrats ETF; 0.40% for S&P MidCap 400 Dividend Aristocrats ETF; 0.40% for the Russell 2000 Dividend Growers ETF; 0.45% for Large Cap Core Plus; 0.45% for DJ Brookfield Global Infrastructure ETF; 0.50% for MSCI EAFE Dividend Growers ETF; 0.50% for High Yield—Interest Rate Hedged; 0.55% for MSCI Europe Dividend Growers ETF; 0.60% for MSCI Emerging Markets Dividend Growers ETF; 0.65% for Crude Oil Strategy ETF; 0.65% for Decline of the Retail Store ETF; 0.65% for Long Online/Short Stores ETF; 0.75% for Managed Futures Strategy ETF; 0.    % for the Bitcoin Futures Strategy ETF; 0.    % for the Short Bitcoin Futures Strategy ETF; 0. % for the Blockchain/Bitcoin Strategy ETF; and 0.    % for the Bitcoin Futures/Equity Strategy ETF.
Since a portion of the Fund’s assets are invested in short positions in bitcoin futures contracts, the Fund will likely decline in value when the price of bitcoin futures contracts goes up (unless such losses are offset by gains in the value of the Fund’s positions in other investments), a result that is the opposite from the results of taking long positions in bitcoin futures contracts.
Bitcoin relies on blockchain technology. “Blockchain” is a decentralized database. Transactions are grouped in blocks and then chained together through cryptographic links. Blockchain is designed so that the chain can be added to, but not edited. This structure is called a “distributed ledger.” Transactions in the distributed ledger are permanently recorded and can never disappear, although theft and loss of bitcoin can occur. While bitcoin has grown in popularity, it’s still not nearly as widely accepted as traditional currency.

While the DJ Brookfield Global Infrastructure ETF and the Global Listed Private Equity ETF anticipate that, under normal market conditions, each Fund will invest primarily (i.e., at least 40% of its “assets” as defined above) in securities issued by issuers organized or located outside the United States (“foreign issuers”), to the extent that foreign issuers ever comprise less than 40% of such Fund’s assets for an extended period of time (i.e., six months), the Fund will take steps to: (i) either change its name; or (ii) change its benchmark.

Assume it is January 3, 2015. Bob and Ann both want to trade at Bitcoin Futures Exchange (BFE). BFE offers 3 different contracts: one expiring and settling on Friday January 9 ('weekly'), another expiring Friday January 16th ('biweekly'), and finally one expiring in March 27 ('quarterly').  Each contract is worth 1 bitcoin notionally.  BFE has a policy that traders have to put 20% of margin down to enter a trade, so Bob and Ann deposit 0.2btc to their BFE accounts as they only want to trade 1 contract.
Traders A and B in the previous example are hedgers. However, futures contracts, once they exist, can also be bought and sold in their own right. This is where futures get interesting for speculators. Say that Speculator X believes the price of a ton of pork belly will rise to 1,200 USD in 3 months’ time, so buying the futures contract at 1,000 USD is a good deal. He can then sell the contract to bacon producers who want to buy pork bellies at 1,000 USD. The option to buy at a specified price in the future is known as a call option. The price of call options rise when traders assume that the price of the underlying asset will rise.
