“Given increasing client interest in the evolving cryptocurrency markets, we have decided to introduce a bitcoin futures contract,” said Terry Duffy, CME Group Chairman and Chief Executive Officer. He further added, “As the world's largest regulated FX marketplace, CME Group is the natural home for this new vehicle that will provide investors with transparency, price discovery and risk transfer capabilities.”

interest, taxes, dividends (including dividend expenses on securities sold short), litigation, indemnification, expenses associated with investment in other funds as permitted by the then current registration statement, and extraordinary expenses as determined under generally accepted accounting principles) to the extent total annual Fund operating expenses, as a percentage of average daily net assets, exceed 0.95% through September 30, 2018 (0.30% for the Inflation Expectations ETF, 0.60% for the Global Listed Private Equity ETF, 0.50% for the Short Term USD Emerging Markets Bond ETF and the CDS Short North American HY Credit ETF, and 0.75% for the Merger ETF each through September 30, 2018. ProShare Advisors, on behalf of the Morningstar Alternatives Solution ETF, has contractually agreed to waive investment advisory and management services fees and to reimburse other expenses (exclusive of transaction costs, interest, taxes, dividends (including dividend expenses on securities sold short), litigation, indemnification, expenses associated with investment in other funds as permitted by the then current registration statement, and extraordinary expenses as determined under generally accepted accounting principles but inclusive of acquired fund fees and expenses) to the extent total annual Fund operating expenses, as a percentage of average daily net assets, exceed 0.95% through September 30, 2018. After such date, the expense limitation may be terminated or revised by ProShare Advisors. Amounts waived or reimbursed in a particular contractual period may be recouped by ProShare Advisors within five years of the end of that contractual period, however, such recoupment will be limited to the lesser of any expense limitation in place at the time of recoupment or the expense limitation in place at the time of waiver or reimbursement.
At the expiration of the contract you are trading, all positions get closed out and settled. Different exchanges use different anchors to settle against. To avoid manipulation, most of them use an index. OKCoin uses a custom 6-exchange index (3 chinese, 3 Western), while BitMEX, Deribit, Coinpit, and CryptoFacilities use a multi-spot-exchange Index to settle all of its contracts at expiration. This minimizes the risk of any manipulation if contracts settled on a single exchange's price, but it also makes it more difficult to manage your hedges since there's no way to "buy" or "sell" an index. No system is perfect, and each one offers different unique pro's and con's, just like your selection of contract type and length. So depending on your case you may want something different than someone else.
  •   Intellectual property claims. A proliferation of recent startups attempting to apply blockchain technology in different contexts means the possibility of conflicting intellectual property claims could be a risk to an issuer, its operations or its business. This could also pose a risk to blockchain platforms that permit transactions in digital securities.
Hey Will. Thanks for the helpful guide! I’ve just gotten into crypto and found this info extremely useful. Just a question regarding how you keep your alt coins safe. As far as I can tell, you can’t keep many of these alt coins on a Trezor hard wallet, so do you just use something like My Ether Wallet instead? Cheers mate! Here’s to a cracking 2018!!
If you want to speculate on the price of a cryptocurrency then the use of a Contract for Difference (CFD) is an option to consider. You won’t actually own the cryptocurrency, which means you don’t face the hassle and hurdles of trying to buy via one of the unregulated exchanges. Instead, a CFD is a financial instrument which allows you to speculate on price movements.

The Fund will periodically adjust its holdings in order to maintain inverse exposure to bitcoin futures contracts. As the price of bitcoin futures contracts declines, net assets of the Fund will generally increase resulting in inverse exposure that is less than the value of the Fund’s assets. Conversely, when the price of bitcoin futures contracts increases, net assets of the Fund will generally decrease resulting in inverse exposure that is more than the value of the Fund’s assets, and the Fund’s inverse exposure will be periodically adjusted to restore approximately equivalent inverse exposure.
participating in a distribution (as opposed to engaging in ordinary secondary market transactions), and thus dealing with the Fund’s shares as part of an “unsold allotment” within the meaning of Section 4(3)(C) of the Securities Act, will be unable to take advantage of the prospectus delivery exemption provided by Section 4(3) of the Securities Act.

A Fund may in its discretion exercise its option to redeem such Shares in cash, and the redeeming shareholder will be required to receive its redemption proceeds in cash. In addition, an investor may request a redemption in cash which a Fund may, in its sole discretion, permit. In either case, the investor will receive a cash payment equal to the NAV of its Shares based on the NAV of Shares of the relevant Fund next determined after the redemption request is received in proper form (minus a redemption Transaction Fee and additional charge for requested cash redemptions, to offset the Fund’s brokerage and other transaction costs associated with the disposition of Fund Securities).
The idea is simple; if the future is trading above the underlying asset (Bitcoin) today, we buy the asset and sell the future, thus receiving cash and locking in a profit. Then on the delivery date, we sell the bitcoin to cover the costs of settling the futures contract. For the deal to be profitable, the price difference has to be large enough to cover interest between today and the delivery date as well as all costs fees.

When you hear "margin", you may be thinking that you are borrowing money to trade bitcoin futures. This is not quite true. A key feature of these futures contracts is that the leverage comes from counterparties providing it to one another, not from the exchange lending funds and not from any bitcoin being lent from third parties. The contracts are simply like stocks with a market price, which represents the agreements between traders to take the opposing sides of where price of bitcoin will go, so no actual bitcoins are being exchanged per se, however the profit and loss between counterparties is very real!


Orders to redeem Creation Units outside the Clearing Process (other than for Global Fund orders), including all cash-only redemptions, must be delivered through a DTC Participant that has executed the Authorized Participant Agreement. A DTC Participant who wishes to place an order for redemption of Creation Units to be effected outside the Clearing Process need not be a “participating party” under the Authorized Participant Agreement, but such orders must state that the DTC Participant is not using the Clearing Process and that the redemption of Creation Units will instead be effected through a transfer of Shares directly through DTC. A redemption order for a Fund must be received by the cut-off times set forth in “Redemption Cut-Off Times” above. The order must be accompanied or preceded by the requisite number of Shares of Funds specified in such order, which delivery must be made through DTC to the Custodian by the second Business Day (T+3) following such transmittal date. All other procedures set forth in the Authorized Participant Agreement must be properly followed in order to receive the next determined NAV.

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.
The Fund pays transaction costs, such as commissions, when it buys and sells securities (including through the Subsidiary, as defined below) or “turns over” its portfolio. A higher portfolio turnover rate for the Fund or the Subsidiary may indicate higher transaction costs and may result in higher taxes when the Fund’s shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the example above, affect the Fund’s performance. The Fund has not yet commenced operations as of the date of this Prospectus. Thus, no portfolio turnover information is provided for this Fund.

•   Any distributions from income or short-term capital gains that you receive generally are taxable to you as ordinary dividends for federal income tax purposes. Ordinary dividends you receive that a Fund reports as “qualified dividend income” may be taxed at the same rates as long-term capital gains, but will not be considered long-term capital gains for other federal income tax purposes, including the calculation of net capital losses.
A Bitcoin (spot or futures) exchange (like any online trading firm) charges its clients a fee to carry out trading activities. As exchanges face the risk of hacking and theft, it is wise not to trust an exchange with all your coins. You should split and keep part of them in other devices or cold storage. Now with bitcoin futures being offered by some of the most prominent marketplaces, investors, traders and speculators are all bound to benefit. These centralized marketplaces will facilitate trade based on a trader’s outlook for bitcoin prices, gain exposure to bitcoin prices or hedge their existing bitcoin positions. Overall, the launching of bitcoin futures by Cboe and CME will facilitate price discovery and price transparency, enable risk-management via a regulated bitcoin product and give a further push to bitcoin as an accepted asset class. (For more, see: The Risks Of Buying Bitcoins.)
To purchase or redeem through the Clearing Process, an Authorized Participant must be a member of NSCC that is eligible to use the Continuous Net Settlement system. For purchase orders placed through the Clearing Process, the Authorized Participant Agreement authorizes the Distributor to transmit through the Funds’ transfer agent (the “Transfer Agent”) to NSCC, on behalf of an Authorized Participant, such trade instructions as are necessary to effect the Authorized Participant’s purchase order. Pursuant to such trade instructions to NSCC, the Authorized Participant agrees to deliver the requisite Deposit Securities and the Balancing Amount to the Trust, together with the Transaction Fee and such additional information as may be required by the Distributor.

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.
This mega-powerful currency has not only opened the gate for other currencies, but also leads the cryptocurrency world with pride. It is governed to make sure no extra Bitcoin is produced, as a maximum quantity of 21 Million Bitcoin units was agreed to. When introduced, the rate was $1 to 1,309 BTC. The wheel has turned, and when Bitcoin reached the all-time high of $19,783.21 in 2017, it was certainly a meaningful milestone for Satoshi Nakamoto, the creator of Bitcoin.
The policy for each Fund regarding purchases and sales of securities is that primary consideration will be given to obtaining the most favorable prices and efficient executions of transactions. Consistent with this policy, when securities transactions are effected on a stock exchange, the policy is to pay commissions that are considered fair and reasonable without necessarily determining that the lowest possible commissions are paid in all circumstances. The Advisor believes that a requirement always to seek the lowest possible commission cost could impede effective portfolio management and preclude the Fund and the Advisor from obtaining a high quality of brokerage and execution services. In seeking to determine the reasonableness of brokerage commissions paid in any transaction, the Advisor relies upon its experience and knowledge regarding commissions generally charged by various brokers and on its judgment in evaluating the brokerage and execution services received from the broker. Such determinations are necessarily subjective and imprecise, as in most cases an exact dollar value for those services is not ascertainable. In addition to commission rates, when selecting a broker for a particular transaction, the Advisor considers but is not limited to the following efficiency factors: the broker’s availability, willingness to commit capital, reputation and integrity, facilities reliability, access to research, execution capacity and responsiveness.

Subject to the general supervision by the Board, the Advisor is responsible for decisions to buy and sell securities and derivatives for each of the Funds and the selection of brokers and dealers to effect transactions. Purchases from dealers serving as market makers may include a dealer’s mark-up or reflect a dealer’s mark-down. Purchases and sales of U.S. government securities are normally transacted through issuers, underwriters or major dealers in U.S. government securities acting as principals. Such transactions, along with other fixed income securities transactions, are made on a net basis and do not typically involve payment of brokerage commissions. The cost of securities purchased from an underwriter usually includes a commission paid by the issuer to the underwriters; transactions with dealers normally reflect the spread between bid and asked prices; and transactions involving baskets of equity securities typically include brokerage commissions. As an alternative to directly purchasing securities, the Advisor may find efficiencies and cost savings by purchasing futures or using other derivative instruments like total return swaps or forward contracts. The Advisor may also choose to cross -trade securities between clients to save costs where allowed under applicable law.
When Bitconnect was exposed as a 100% scam and was shut down, the price dropped vertically to almost zero. But then, it bounced back up by something like 15-30 percent, and it kept going up for a couple of days. This is caused, in my opinion, by the fact that bots and cavemen technical analysts, who never follow the news, look at the chart and think “this is a great time to buy”.

I’m a nomad from The States, currently residing in Indonesia. Can you suggest the best global service for wallets/exchanges? In The States it’s Coinbase but its supported countries are extremely limited for my needs limited. I need something I can access in basically any country without issue. I know there are a options out there, but I wanted to get you opinion of how other travelers have gotten past this.
Fixed margin will isolate your margin to the individual position you have made in an instrument. So if you have 1 bitcoin in your account and you put 0.2btc margin for a Weeklies Futures long position, and it gets margin-called, you still have the 0.8btc left. However, if you're on cross-margin, also known as portfolio value margin, then your whole balance on the site is going to be used to back all your positions, and if you get margincalled, it's because you have run out of money on your whole account.
I’m an elderly gentleman, closing in on 68 years of age. My son introduced me to Crypto in late 2012. After doing a lot of researching Btc I felt strongly that It had a lot of growth and potential ahead of it. So my son and I built my 1st rig and I started mining in January 2013, pulled $5,000 from my IRA and bought Btc at $13.44 and have never looked back since. The sweetest sound that I’ve ever heard was the clink of my 1st mined Bitcoin way back when. That was as satisfying a note as there ever was on any musical scale. Nothing but happy days ahead since. Don’t get me wrong, there have been bumps in this Crypto highway, the demise of the Silk Road, Mt Gox, DAO hack to name a few but as a HOLDer (holding on for the long duration) not a HODLer (hanging on for dear life) and not day trading, has rewarded me with quite a decent profit. It just takes a lot of patience (Sisu) and doing your research with due diligence. I have since invested in Ethereum (Dec 2015), Monero (Jan 2016) and lately Omisego (July 2017) all purchased from some of my profits from Btc to go along with my newly acquired free Bch and recently free Omg. I’m currently operating 3 rigs equipped with 6 gpus each. 2 mining Eth and 1 Monero for now, all of which will be re-evaluated after Metropolis kicks in to see which direction I go from here. So I ‘m back to doing more research in order to help with my next moves but I’ll always be a strong believer in Ethereum which is where I’ve made my money so far. HOLDing on to the rest for now. Btc $5,000-10,000, Eth $2,500- 5,000, Monero $200-400, Omg $100-1,000 no one ever really knows but MY research says yes and so far MY research has not proven me wrong. Bought Btc at $13.44, Eth at .80, Monero at .48, Omg at .43 Bch for free. No where to go but up for me. Just biding my time. It’s taken me over 4 and a half years to get here but I’ve made over $4,000,000 so far with just my original investment plus the cost of my rigs and I’m still sitting on a lot more. Taking a position and HOLDing is where the real profit is and it isn’t going to happen overnight. So if you want aggravation and ulcers go ahead and day trade, try and beat the Market I wish you luck but the real money comes with Research, HOLDing and Patience. Hope this advice helps because in the long run what it all comes down to, its just Eths, You and Me hopefully making the right decisions.
On October 31, 2017, CME Group, the world's leading and most diverse derivatives marketplace, had announced its intent to launch bitcoin futures in the fourth quarter of 2017. “CME Group's Bitcoin futures will be available for trading on the CME Globex electronic trading platform, and for submission for clearing via CME ClearPort, effective on Sunday, December 17, 2017 for a trade date of December 18” as per CME’s officials statement.

Don’t FOMO. This is a spot that people most frequently lose money on. A dash of manipulation, two tablespoons of media hype, a cup of CME and CBOE announcements, and a generous handful of FOMO drove Bitcoin prices from $10,000 to $20,000 in December. Since that time, Bitcoin fell to a low of $9,000 and is currently sitting at around $11,000. It’s easy to look back and say, “if only I waited one month, then I could’ve bought at $9,000 instead of waiting for Bitcoin to hit $20,000 again for me to break even.” But the reality is, the combination of 1) being greedy, 2) investing blindly, and 3) FOMO were likely large contributors to the purchase at an all-time-high. Even in the crazy world of cryptocurrency, if a coin pumps that quickly, it will correct — it’s a matter of time. Speculative pumps are almost always followed by dips. While trying to jump onto a train going full speed sounds like something straight out of a James Bond movie, I’m sure most of us can agree we would probably save some limbs if we just waited for it at the next stop.

Transactions that occur through the use and exchange of these altcoins are independent from formal banking systems, and therefore can make tax evasion simpler for individuals. Since charting taxable income is based upon what a recipient reports to the revenue service, it becomes extremely difficult to account for transactions made using existing cryptocurrencies, a mode of exchange that is complex and difficult to track.[84]
BitMEX also has a weekly rebalancing for all their contracts, but currently their most popular product is the Daily 100x maximum leverage contract. This settles daily, but otherwise the rest of the contracts are handled on Friday, a little bit after OKCoin's 8:00AM UTC. See this website to get a countdown to the settlements on the different exchanges. The policies of exchanges are changing often so this information may be outdated by the time you read it (though we will try to keep it as up to date as possible).

A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.[1][2][3] Cryptocurrencies are a kind of alternative currency and digital currency (of which virtual currency is a subset). Cryptocurrencies use decentralized control[4] as opposed to centralized digital currency and central banking systems.[5] The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.[6][7]
EDIT: #10 Bonus (Suggested by @kerstenwirth ) — always check the ticker symbol. Ticker symbols are not universal, and may vary from exchange to exchange in rare cases. Those cases, though, can come back to bite you. For example, Bitcoin Cash trades on some exchanges as BCH, while it trades on others as BCC. BCC is also the ticker symbol for BitConnect, which was recently outted as a Ponzi Scheme. If you bought BCC under the impression was Bitcoin Cash, you would’ve lost a lot of money.
The NAV per share of each Fund is computed by dividing the value of the net assets of such Fund (i.e., the value of its total assets less total liabilities) by its total number of Fund shares outstanding. Expenses and fees are accrued daily and taken into account for purposes of determining NAV. The NAV of each Fund is calculated by JPMorgan Chase Bank, National Association. The NAV of each Fund is generally determined each business day at the close of regular trading of the                    (ordinarily 3:00 p.m. Eastern time). The Fund’s investments are generally valued at their market value using information provided by a pricing service or market quotations. Short-term securities are valued on the basis of amortized cost or based on market prices. In addition, routine valuation of certain other derivatives is performed using procedures approved by the Board.
While cryptocurrencies are digital currencies that are managed through advanced encryption techniques, many governments have taken a cautious approach toward them, fearing their lack of central control and the effects they could have on financial security.[99] Regulators in several countries have warned against cryptocurrency and some have taken concrete regulatory measures to dissuade users.[100] Additionally, many banks do not offer services for cryptocurrencies and can refuse to offer services to virtual-currency companies.[101] Gareth Murphy, a senior central banking officer has stated "widespread use [of cryptocurrency] would also make it more difficult for statistical agencies to gather data on economic activity, which are used by governments to steer the economy". He cautioned that virtual currencies pose a new challenge to central banks' control over the important functions of monetary and exchange rate policy.[102] While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if bitcoins are lost or stolen.[103] One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.
  negative impact on the price of such contracts. In order to comply with such limits, the Fund may be required to reduce the size of its outstanding positions or not enter into new positions that would otherwise be taken for the Fund. This could potentially subject the Funds to substantial losses or periods in which the Fund does not accept additional Creation Units.

Ann then goes on BFE and she wants to short on bitcoin at market price. She sees that only the January 9 contract has any orders. She could put a limit order in the orderbook if she wanted. However, she sees Bob's bid in the orderbook and decides to fill it, and uses her 0.2btc as margin to collateralize this position. She has just opened a position worth 1 bitcoin that has 5x leverage, and so has Bob.
A key attribute of a futures market is how its contract’s prices vary by expiration date. The succession of futures prices over time is called the “term structure”. If supply is stable (no seasonality or shortages) then typically futures prices will increase with expirations further in the future. This term structure configuration is called “contango” and it accounts for the fact that carry costs (e.g., time value of money) and profit expectations increase with time. Unless there are big changes in interest rates or the way that Bitcoin exchanges work I expect the level of contango in the Bitcoin futures term structure to be small. Bitcoins don’t cost much to hodl (once you have your hardware wallet) and there’s no apparent seasonality. The chart below from VIX Central shows a typical Bitcoin term structure (click on chart to get current data):
