Crypto derivatives were naturally discovered as an interesting addition to cryptocurrency exchanges first – probably as individual contracts between interested investors on these exchanges. Nowadays, there are already a couple of exchanges that offer crypto derivatives trading as a standard feature: BitMEX is the current market leader, according to The Merkle News; others are OKCoin, Crypto Facilities, Coinpit, and Deribit, as well as LedgerX (the first regulated cryptocurrency exchange in the US).

The Funds may invest in both sponsored and unsponsored depositary receipts. Certain depositary receipts, typically those designated as “unsponsored,” require the holders thereof to bear most of the costs of such facilities, while issuers of “sponsored” facilities normally pay more of the costs thereof. The depository of an unsponsored facility frequently is under no obligation to distribute shareholder communications received from the issuer of the deposited securities or to pass through the voting rights to facility holders with respect to the deposited securities, whereas the depository of a sponsored facility typically distributes shareholder communications and passes through the voting rights.
The CME considers a hard fork of the Bitcoin Blockchain where both forks continue to be actively mined and traded but may not be fungible with each other, as an unusual and extreme circumstance. As such, CME provides that Crypto Facilities Ltd. (CME’s administrator) shall be responsible for recommending the necessary actions and responses to ensure the relevance and integrity of the Bitcoin Pricing Products.
The ProShares Bitcoin/Blockchain Strategy ETF contains portfolio investments that are primarily listed on foreign markets. To the extent the Fund’s portfolio investments trade in foreign markets on days when the Fund is not open for business or when the primary exchange for its shares is not open, the value of the Fund’s assets may vary on days when shareholders may not be able to purchase or sell Fund shares and Authorized Participants may not be able to create or redeem Creation Units. Also, certain portfolio investments may not be traded on days the Fund is open for business.
The legal status of cryptocurrencies varies substantially from country to country and is still undefined or changing in many of them. While some countries have explicitly allowed their use and trade,[66] others have banned or restricted it. According to the Library of Congress, an "absolute ban" on trading or using cryptocurrencies applies in eight countries: Algeria, Bolivia, Egypt, Iraq, Morocco, Nepal, Pakistan, and the United Arab Emirates. An "implicit ban" applies in another 15 countries, which include Bahrain, Bangladesh, China, Colombia, the Dominican Republic, Indonesia, Iran, Kuwait, Lesotho, Lithuania, Macau, Oman, Qatar, Saudi Arabia and Taiwan.[67] In the United States and Canada, state and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating "bitcoin scams" and ICOs in 40 jurisdictions.[68]
As we have seen above, a futures contract has an expiration date. This is the date on which you can purchase the ton of pork bellies for 1,000 USD – this is called a physical settlement. Alternatively, futures contracts can be settled with cash as well. In these contracts, you receive the difference between the current price of the underlying asset and the price in your contract as cash.

Were Centra's tokens securities? Well, yes, obviously. We talked last week about the Securities and Exchange Commission's enforcement action against Munchee, an initial coin offering vaguely similar to Centra's in that it featured "utility tokens" to be used in a blockchain ecosystem that did not yet exist, sold on promises of speculative returns. The SEC brusquely and correctly dismissed the notion that such "utility tokens" were not securities, and I suspect any court will agree. Also, while Centra occasionally remembered to call its tokens "utility-based tokens" and "not securities, shares or investments," it often forgot. From the complaint:
Upon entering into a futures contract, each Fund will be required to deposit with the broker an amount of cash or cash equivalents in the range of approximately 5% to 10% of the contract amount for equity index futures and in the range of approximately 1% to 3% of the contract amount for treasury futures (these amounts are subject to change by the exchange on which the contract is traded). This amount, known as “initial margin,” is in the nature of a performance bond or good faith deposit on the contract and is returned to the Fund upon termination of the futures contract, assuming all contractual obligations have been satisfied. Subsequent payments, known as “variation margin,” to and from the broker will be made daily as the price of the index underlying the futures contract fluctuates, making the long and short positions in the futures contract more or less valuable, a process known as “marking-to-market.” At any time prior to expiration of a futures contract, a Fund may elect to close its position by taking an opposite position, which will operate to terminate the Fund’s existing position in the contract.
When the Advisor determines that the price of a security is not readily available or deems the price unreliable, it may, in good faith, establish a fair value for that security in accordance with procedures established by and under the general supervision and responsibility of the Trust’s Board of Trustees. The use of a fair valuation method may be appropriate if, for example, market quotations do not accurately reflect fair value for an investment, an investment’s value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded (for example, a foreign exchange or market), a trading halt closes an exchange or market early, or other events result in an exchange or market delaying its normal close.
In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt.[38] This arms race for cheaper-yet-efficient machines has been on since the day the first cryptocurrency, bitcoin, was introduced in 2009.[38] With more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs. Thus the value of the currency obtained for finding a hash often does not justify the amount of money spent on setting up the machines, the cooling facilities to overcome the enormous amount of heat they produce, and the electricity required to run them.[38][39]

Cryptocurrency is also used in controversial settings in the form of online black markets, such as Silk Road. The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[84]
The Board has approved a Distribution and Service Plan under which each Fund may pay financial intermediaries such as broker-dealers and investment advisers (“Authorized Firms”) up to 0.25%, on an annualized basis, of average daily net assets of the Fund as reimbursement or compensation for distribution-related activities with respect to the Shares of the Fund and shareholder services. Under the Distribution and Service Plan, the Trust or the Distributor may enter into agreements (“Distribution and Service Agreements”) with Authorized Firms that purchase Shares on behalf of their clients.

​Trading these futures instead of actual bitcoins is smart because you are able to access higher leverage by entering contracts with counterparties, while keeping your coins safe in cold storage or elsewhere. Additionally, unlike trading margin on Kraken or Bitfinex, you do NOT have to pay interest on the leverage you have! This is the result of the counterparty structure of futures. High leverage trading, low-fees, and high profit potential.

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.
