Example: spot BTC/USD is $500. A weekly futures contract expires in 7 days. What should it be trading at? Using a 5% APY USD rate and a 1% BTC rate, you borrow $500, invest in 1 BTC. 7 days later, you will have paid $0.48 in USD interest, and earned 0.0002 BTC ($0.10 at current spot price).  A reasonable price for the futures contract would be somewhere more than $0.38 (the difference between the $0.48 interest paid $0.10 expected interest received) above spot price. This is because you would be able to lock in the sale of the 1 BTC that is being invested at a higher price. You know you have to pay back $500 plus interest, and you earn a little interest on the bitcoin, so any futures contract trading significantly above that $0.38 deficit in the spot play would give you a great arbitrage opportunity:

BitMEX is a derivatives exchange that offers leveraged contracts that are bought and sold in Bitcoin. This is a platform that provides trading in bitcoin derivatives. The derivative traded is a perpetual swap contract, which is a derivative product similar to a traditional Futures Contract. Swap contracts trade like spots, tracking the underlying assets.

The Funds may make short sales “against the box,” i.e., when a security identical to or convertible or exchangeable into one owned by a Fund is borrowed and sold short. Whenever a Fund engages in short sales, it earmarks or segregates liquid securities or cash in an amount that, when combined with the amount of collateral deposited with the broker in connection with the short sale, equals the current market value of the security sold short. The earmarked or segregated assets are marked-to-market daily.
Elaborating a bit on the concept of Cryptocurrency and the blockchain effect before we move onto the central theme. As put in words by Daniel Gasteiger on the topic ‘Blockchain Demystified’ at TEDxLausanne,‘A blockchain is nothing but a database, a database that is public, therefore not owned by anybody. Distributed hence not stored centrally on one computer but on many computers across the world. Constantly synchronized to keep the transactions up to date and secured overall by the art of cryptography to make it tamper proof and hacker proof. These four features make this technology exceptional.’ Daniel’s strong belief in the solidarity of the concept of Cryptocurrency motivated him to leave his full-fledged career of 20 years in financial services to focus on the concept of Blockchain.

For each of the following Funds that hold Non-U.S. Investments: the DJ Brookfield Global Infrastructure ETF; the Global Listed Private Equity ETF; the MSCI EAFE Dividend Growers ETF; the MSCI Europe Dividend Growers; the Short Term USD Emerging Markets Bond ETF; and the Merger ETF (each a “Global Fund” and collectively the “Global Funds”), when a purchase order is placed, the Distributor will inform the Advisor and the Custodian. The Custodian shall cause local sub-custodians of the applicable Global Fund to maintain an account into which the Authorized Participant shall deliver, on behalf of itself or the party on whose behalf it is acting, the Deposit Securities “free of payment,” with any appropriate adjustments as advised by the Trust, in accordance with the terms and conditions applicable to such account in such jurisdiction. If applicable, the sub-custodian(s) will confirm to the Custodian that the required Deposit Securities have been delivered and the Custodian will notify the Advisor and Distributor. The Authorized Participant must also make available to the Custodian no later than 12:00 noon Eastern Time (or earlier in the event that the relevant Exchange or the relevant bond markets close early) by the second Business Day after the order is deemed received through the Federal Reserve Bank wire transfer system, immediately available or same day funds in U.S. dollars estimated by the Trust to be sufficient to pay the Balancing Amount next determined after acceptance of the purchase order, together with any applicable Transaction Fees. For Global Funds, the Index Receipt Agent will not make available through the NSCC on each Business Day, the list of the names and the required number of shares of each Deposit Security to be included in the current Portfolio Deposit.
It bears repeating -- when trading futures on leverage, you are not "borrowing" the money, so you don't have to pay a financing rate on your positions. Even though you are 100x exposed, you don't have to pay 100x financing (unless you're trading the perpetual swap, which is not a futures contract, but has similar characteristics). Since bitcoin futures do tend to trade at a premium, you are in a way paying an implied interest rate in the contract, because if you want to go long, you have to pay above spot, so you pay the interest up front in the contract, in a way.
CORPORATE DEBT SECURITIES. Corporate debt securities are fixed income securities issued by businesses to finance their operations, although corporate debt instruments may also include bank loans to companies. Notes, bonds, debentures and commercial paper are the most common types of corporate debt securities, with the primary difference being their maturities and secured or unsecured status. Commercial paper has the shortest term and is usually unsecured. The broad category of corporate debt securities includes debt issued by domestic or foreign companies of all kinds, including those with small-, mid- and large-capitalizations. Corporate debt may be rated investment-grade or below investment-grade and may carry variable or floating rates of interest.

“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.
Options give the holder of the option the right to buy (or to sell) a position in a security or in a contract to the writer of the option, at a certain price. There may be imperfect correlation, or even no correlation, between price movements of an options contract and price movements of investments underlying an options contract. Lack of correlation (or tracking) may be due to factors unrelated to the value of the investments being hedged, such as speculative or other pressures on the markets in which these instruments are traded. Consequently, the effectiveness of bitcoin options in providing exposure to the price movements of options will depend, in part, on the degree of correlation between price movements in the derivatives and price movements in underlying bitcoin markets. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Sub-Adviser, thus limiting the ability to implement the Fund’s strategies. Options are also particularly subject to leverage risk and can be subject to liquidity risk.

•   Compounding Risk — In the course of managing the Fund’s investments, ProShare Advisors will need to periodically adjust the Fund’s holdings in order to maintain investment exposure approximately equivalent to the Fund’s assets. This process entails obtaining additional inverse exposure as the Fund experiences gains, and reducing inverse exposure as the Fund experiences losses. The higher the volatility of the bitcoin futures contracts in which the Fund invests, the more such rebalancing can adversely affect the Fund’s performance.

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.

Trader A is a producer of pork bellies. In order to insure herself against a price drop in pork bellies in the future, she enters a futures contract with Trader B. Trader B uses these pork bellies to manufacture sliced breakfast bacon. Thus, he is not worried that prices might fall in the future – his worry is that prices will go up. Both traders agree that Trader A will sell a metric ton of pork bellies for 1,000 USD 3 months from now. This increases security for both of their businesses. Because a futures contract is a binding contract between two parties, neither party can drop out of the contract: Even if the price for pork bellies is 1,200 USD at the time of execution, trader A is still contractually obliged to sell for 1,000 USD.
