Source: MV Index Solutions GmbH (MVIS®). MVIS is a wholly owned subsidiary of Van Eck Associates Corporation. Data as of December 8, 2017 (synthesized data from BitMEX, OKCoin, CryptoFacilities, and BTCC which represents non-U.S. listed bitcoin futures trading on these exchanges). Not intended to be a forecast of future events, a guarantee of future results or investment advice. Current market conditions may not continue.  
As discussed above in “Investment in a Subsidiary”, each of the Managed Futures Strategy ETF, the Crude Oil Strategy ETF the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF (each, a “Parent Fund”) intends to achieve commodity exposure through investment in a wholly-owned foreign subsidiary (each a “Subsidiary”). Each Subsidiary is classified as a corporation and is treated as a “controlled foreign corporation” (“CFC”) for U.S. federal income tax purposes. Each Parent Fund will limit its investments in its Subsidiary in the aggregate to 25% of the Parent Fund’s total assets. Each Parent Fund does not expect that income from its investment in its Subsidiary will be eligible to be treated as qualified dividend income or that distributions from its Subsidiary will be eligible for the corporate dividends-received deduction.
The Fund is an actively managed exchange traded fund. The Fund seeks to achieve its investment objective by investing substantially all of its assets in a combination of (i) the equity securities of blockchain technology companies, (ii) bitcoin futures, options and swap contracts that provide exposure to the price movements of bitcoin (“Bitcoin Derivatives”) and (iii) bitcoin related securities, such as bitcoin linked exchange traded notes (“ETNs”), funds and trusts (“Bitcoin Securities”) (collectively, with Bitcoin Securities, “Bitcoin Investments”). The Fund targets a minimum of 30% exposure to Bitcoin Investments. The Fund’s other assets will be invested in the equity securities of blockchain technology companies — companies that the Fund’s investment advisor determines are well-positioned to benefit from blockchain technology. The securities of blockchain technology companies may be listed on U.S. or non-U.S. exchanges and must meet certain minimum capitalization and liquidity requirements. The Fund intends to concentrate its investment in blockchain technology companies and/or technology companies.
Most swap agreements entered into by a Fund (but generally not CDS) calculate and settle the obligations of the parties to the agreement on a “net basis” with a single payment. Consequently, a Fund’s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”). Other swap agreements, such as CDS, may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of the reference entity.
CryptoFacilities, Coinpit, and BitMEX has a realtime profit realisation, while OKCoin and Deribit has weekly rebalancing scheduled for all contract lengths. It's important to note that on all of these exchanges, all the futures and forwards are non-deliverable and have expiration at various times. Despite this, OKCoin uses "delivery" as their term for expiration settlement of a contract, and "settlement" for the weekly rebalancing of the Pnl for higher length contracts. Since we are stuck with this unprofessional Chinese exchange being the dominant market player in futures, we have to focus on their use of the terminology, but BitMEX and CryptoFacilities have very impressive and professional setups that use well documented procedures. Always read the documentation of any exchange you're using and the contract specifications of the individual product you're using.

XBT futures are cash-settled contracts based on the Gemini's auction price for bitcoin, denominated in U.S. dollars. Gemini Trust Company, LLC (Gemini) is a digital asset exchange and custodian founded in 2014 that allows customers to buy, sell, and store digital assets such as bitcoin, and is subject to fiduciary obligations, capital reserve requirements, and banking compliance standards of the New York State Department of Financial Services.

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”.

The Registrant (also, the “Trust”) is organized as a Delaware business trust is operated pursuant to an Amended and Restated Declaration of Trust, dated December 13, 2010 (the “Declaration of Trust”), that permits the Registrant to indemnify every person who is, or has been, a Trustee, officer, employee or agent of the Trust, including persons who serve at the request of the Trust as directors, trustees, officers, employees or agents of another organization in which the Trust has an interest as a shareholder, creditor or otherwise (hereinafter referred to as a “Covered Person”), shall be indemnified by the Trust to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been such a Trustee, director, officer, employee or agent and against amounts paid or incurred by him in settlement thereof. This indemnification is subject to the following conditions:
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.

The Board of Trustees of the Trust reserves the right to declare a split or a consolidation in the number of Shares outstanding of any Fund, and may make a corresponding change in the number of Shares constituting a Creation Unit, in the event that the per Share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.
ProShares Crude Oil Strategy ETF is an actively managed fund that seeks to provide total return through actively managed exposure to the West Texas Intermediate (“WTI”) crude oil futures markets. The Fund’s strategy seeks to outperform certain index based strategies by actively managing the rolling of WTI crude oil futures contracts. “Rolling” means selling a futures contract as it nears its expiration date and replacing it with a new futures contract that has a later expiration date. The Fund generally selects between WTI crude oil futures contracts with the three nearest expiration dates (known as the front, second and third month contracts) based on ProShare Advisors’ analysis of the liquidity and cost of establishing and maintaining such positions. Each month, the Fund will evaluate this strategy on or about the fifth business day of the month and may roll its position from the fifth through ninth business days into the contract month determined by the Fund’s active investment strategy.

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.
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]
Distributions of Shares shall be made to DTC or its nominee, Cede & Co., as the registered holder of all Shares. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in Shares as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial owners of Shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants. The Trust has no responsibility or liability for any aspects of the records relating to or notices to Beneficial owners, or payments made on account of beneficial ownership interests in such Shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial owners owning through such DTC Participants.

You will then be able to trade futures contracts just like they are bitcoin spot. If price goes up on spot, a good futures exchange will have its contracts also going up in price, and then you can sell and get out. However, the price of the futures contract is dependent on others trading it. So if nobody else is trading it and bringing the market price of the contract along with changes in the underlying asset, then it's useless and you are forced to hold it until settlement to realize any of the profit/loss from the position.
In order to provide current Share pricing information, an Exchange disseminates an updated Indicative Optimized Portfolio Value (“IOPV”) for each Fund. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no warranty as to the accuracy of the IOPVs. IOPVs are expected to be disseminated on a per Fund basis every 15 seconds during regular trading hours of an Exchange.
All three DBRS rating categories for short term debt use “(high)”, “(middle)” and “(low)” as subset grades to designate the relative standing of the credit within a particular rating category. The following comments provide separate definitions for the three grades in the Prime Credit Quality area, as this is where ratings for active borrowers in Canada continue to be heavily concentrated.
Bitcoin has been on a tear this year, surging at least 1,000 percent in 2017. As the cryptocurrency gained even more attention from investors recently, the Commodity Futures Trading Commission announced on Friday that it would allow the CME and Cboe to launch bitcoin futures. The Cboe plans to launch on Dec. 10 and the CME intends to launch on Dec. 18.
The Fund is an actively managed exchange traded fund. The Fund seeks to achieve its investment objective by investing substantially all of its assets in U.S. large capitalization equity securities and bitcoin futures contracts. The Fund is designed to benefit when the prices of U.S. large capitalization equity securities and bitcoin futures contracts increases. The Fund generally seeks to have 70% of the value of its portfolio invested in the equity securities of the 500 largest U.S. public companies and 30% of the value of its portfolio invested in bitcoin futures contracts. The Fund does not invest directly in bitcoin.
Example: If the futures contract price is $400, then you can buy 0.5btc worth of this and if the price of bitcoin goes up to $450 the futures contract price will go up, and the value increases from 0.5 BTC and you can just sell for a profit. Trading a synthetic derivative rather than spot bitcoin allows you to use margin leverage to more easily buy and sell -- the contracts are just a facilitation of the value.

Investments by a Fund in a wholly-owned foreign subsidiary, debt obligations issued or purchased at a discount and certain derivative instruments could cause the Fund to recognize taxable income in excess of the cash generated by such investments, potentially requiring the Fund to dispose of investments (including when otherwise disadvantageous to do so) in order to meet
The NAV of each Fund is typically determined each business day at 3:00 p.m., Eastern Time on days when                    is open for trading. The [            ] Exchange is open every week, Monday through Friday, except when the following holidays are celebrated: New Year’s Day, Martin Luther King, Jr. Day (the third Monday in January), Presidents’ Day (the third Monday in February), Good Friday, Memorial Day (the last Monday in May), Independence Day, Labor Day (the first Monday in September), Thanksgiving Day (the fourth Thursday in November) and Christmas Day. An Exchange may close early on the business day before each of these holidays and on the day after Thanksgiving Day. Exchange holiday schedules are subject to change without notice. If the exchange or market on which a Fund’s investments are primarily traded closes early, the NAV may be calculated prior to its normal calculation time. Creation/ redemption transaction order time cutoffs would also be accelerated.
On 21 November 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USDT from their primary wallet.[89] The company has 'tagged' the stolen currency, hoping to 'lock' them in the hacker's wallet (making them unspendable). Tether indicates that it is building a new core for its primary wallet in response to the attack in order to prevent the stolen coins from being used.

JPMorgan Chase Bank, National Association, One Beacon Street, 19th Floor, Boston, MA 02108, acts as Administrator to the Funds pursuant to an administration agreement dated June 16, 2006, as amended from time to time. The Administrator provides the Funds with all required general administrative services, including, without limitation, office space, equipment, and personnel; clerical and general back office services; bookkeeping and internal accounting; the determination of NAVs; and the preparation and filing of all financial reports, and all other materials, except registration statements and proxy statements, required to be filed or furnished by the Funds under federal and state securities laws. Citi Fund Services Ohio, Inc. (“Citi”), located at 4400 Easton Commons, Suite 200, Columbus, OH 43219, an indirect wholly-owned subsidiary of Citibank N.A., provides regulatory administration services to the Trust (altogether, the “Regulatory Administrative Services”). For its services, Citi is paid a set fee allocated among each of the Funds.

There are also tax risks associated with investments in MLPs. While there are benefits to MLPs that are treated as partnerships for federal income tax purposes, a change to current tax law or in the underlying business of a given MLP could result in the MLP being treated as a corporation for federal income tax purposes. If the MLP were treated as a corporation, the MLP would be required to pay federal income tax on its taxable income, which would reduce the amount of cash available for distribution by the MLP. In addition, because MLPs generally conduct business in multiple states, the Fund may be subject to income or franchise tax in each of the states in which the partnership does business. The additional cost of preparing and filing the tax returns and paying related taxes may adversely impact the Fund’s return.


I used to find it odd that these hypothetical AIs were supposed to be smart enough to solve problems that no human could, yet they were incapable of doing something most every adult has done: taking a step back and asking whether their current course of action is really a good idea. Then I realized that we are already surrounded by machines that demonstrate a complete lack of insight, we just call them corporations. Corporations don’t operate autonomously, of course, and the humans in charge of them are presumably capable of insight, but capitalism doesn’t reward them for using it. On the contrary, capitalism actively erodes this capacity in people by demanding that they replace their own judgment of what “good” means with “whatever the market decides.”
However, there could be a transition stage in which volatility could actually become worse. Large financial trading firms could enter the market to an extent that has not been seen yet, and because bitcoin is so difficult to value (as Warren Buffet put it: “You can’t value bitcoin because it’s not a value-producing asset.”), a lot of different forces will act on its price. Shorts will become more popular, and disagreements on pricing could manifest in the cryptocurrency markets in the form of extreme price jumps, more so than is already commonplace.

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.


You could imagine the spread going the other way, though. If everyone really was clamoring to short bitcoin, and if the futures offered a more convenient way to do it than the bitcoin exchanges, then you'd expect the short sellers to pay a premium to short via futures. Instead of selling a bitcoin at $18,000 today, they'd be willing to sell a synthetic bitcoin for $17,500, paying the spread to an arbitrageur who was willing to do the actual shorting for them. But the fact that the spread is mostly positive, and that bitcoin's price has been mostly going up, suggests that the demand has mostly been for synthetic long positions, not short.
the option to purchase the asset underlying the option at the exercise price if the option is exercised. During the term of the option, the writer may be assigned an exercise notice by the broker-dealer through whom the option was sold. The exercise notice would require the writer to deliver, in the case of a call, or take delivery of, in the case of a put, the underlying asset against payment of the exercise price. This obligation terminates upon expiration of the option, or at such earlier time that the writer effects a closing purchase transaction by purchasing an option covering the same underlying asset and having the same exercise price and expiration date as the one previously sold. Once an option has been exercised, the writer may not execute a closing purchase transaction. To secure the obligation to deliver the underlying asset in the case of a call option, the writer of a call option is required to deposit in escrow the underlying asset or other assets in accordance with the rules of the Options Clearing Corporation (the “OCC”), an institution created to interpose itself between buyers and sellers of options. The OCC assumes the other side of every purchase and sale transaction on an exchange and, by doing so, gives its guarantee to the transaction. When writing call options on an asset, a Fund may cover its position by owning the underlying asset on which the option is written. Alternatively, the Fund may cover its position by owning a call option on the underlying asset, on a share-for-share basis, which is deliverable under the option contract at a price no higher than the exercise price of the call option written by the Fund or, if higher, by owning such call option and depositing and segregating cash or liquid instruments equal in value to the difference between the two exercise prices. In addition, a Fund may cover its position by segregating cash or liquid instruments equal in value to the exercise price of the call option written by the Fund. When a Fund writes a put option, the Fund will segregate with its custodian bank cash or liquid instruments having a value equal to the exercise value of the option. The principal reason for a Fund to write call options on assets held by the Fund is to attempt to realize, through the receipt of premiums, a greater return than would be realized on the underlying assets alone.
Each Fund may purchase or sell futures contracts and options thereon as a substitute for a comparable market position in the underlying securities or to satisfy regulatory requirements. A physical-settlement futures contract generally obligates the seller to deliver (and the purchaser to take delivery of) a specified asset on the expiration date of the contract. A cash-settled futures contract obligates the seller to deliver (and the purchaser to accept) an amount of cash equal to a specific dollar amount (the contract multiplier) multiplied by the difference between the final settlement price of a specific futures contract and the price at which the agreement is made. No physical delivery of the underlying asset is made. The Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF will each invest in cash-settled futures contracts where commodities are the underlying asset. The Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF intend to achieve this exposure through investment in the ProShares Cayman Portfolio I, the ProShares Cayman Crude Oil Portfolio, the ProShares Cayman Bitcoin Futures Strategy Portfolio ProShares Cayman Short Bitcoin Futures Strategy Portfolio, ProShares Cayman Bitcoin Futures/Equity Strategy Portfolio and ProShares Cayman Bitcoin/Blockchain Strategy Portfolio, respectively, which may invest in futures contracts and options thereon.

The primary risks associated with the use of futures contracts are imperfect correlation between movements in the price of the futures and the market value of the underlying assets, and the possibility of an illiquid market for a futures contract. Although each Fund intends to sell futures contracts only if there is an active market for such contracts, no assurance can be given that a liquid market will exist for any particular contract at any particular time. Many futures exchanges and boards of trade limit the amount of fluctuation permitted in futures contract prices during a single trading day. Once the daily limit has been reached in a particular contract, no trades may be made that day at a price beyond that limit or trading may be suspended for specified periods during the day. Futures contract prices could move to the limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and potentially subjecting a Fund to substantial losses. If trading is not possible, or if a Fund determines not to close a futures position in anticipation of adverse price movements, the Fund will be required to make daily cash payments of variation margin. The risk that the Fund will be unable to close out a futures position will be minimized by entering into such transactions on a national exchange with an active and liquid secondary market. In addition, although the counterparty to a futures contract is often a clearing organization, backed by a group of financial institutions, there may be instances in which the counterparty could fail to perform its obligations, causing significant losses to a Fund.
An Authorized Participant may place an order to redeem Creation Units (i) through the Clearing Process, or (ii) outside the Clearing Process. In either case, a redemption order for a Fund must be received by the following cut-off times (which may be earlier if the relevant Exchange or any relevant bond market closes early). In all cases purchase/redeem procedures are at this discretion of the Advisor and may be changed without notice.

For Caspian, creating a crypto trading system that meets the needs of institutional investors is a benefit not only to those traders, but to the entire crypto ecosystem. Providing the infrastructure that institutions need to confidently enter the crypto world sets the stage for a much larger market. This brings needed volume, scale, stability and liquidity — not to mention the kind of credibility that can encourage even more players. In the end, we believe that building an effective trading solution will raise all boats to help crypto live up to its vast potential.
Government regulation could adversely impact the operation of the Bitcoin Network or the use of bitcoin. As bitcoin and other digital assets have grown in popularity and in market size, certain U.S. federal and state governments, foreign governments and self-regulatory agencies have begun to examine the operations of bitcoin, digital assets, the Bitcoin Network, bitcoin users and related issues. Although currently bitcoin is not regulated or is lightly regulated in most countries, including the United States, some countries have, and one or more countries may in the future, take regulatory actions that severely restrict the right to acquire, own, hold, sell or use bitcoin or to exchange bitcoin for fiat currency. Regulation in the U.S. and foreign jurisdictions may restrict the use of bitcoin or otherwise materially impact the global demand for bitcoin. Regulation of initial coin offerings (“ICOs”) and other cryptocurrencies may have an impact the price of bitcoin. If Bitcoin Exchanges become subject to regulation, that may also impact trading in bitcoin as trading may be concentrated in a smaller number of regulated exchanges, which may impact price, volatility and trading volumes. Also, most Bitcoin Exchanges currently require bitcoin trading accounts to be fully funded, but if margin trading is introduced, there may be additional risks, including

Please note these holiday schedules are subject to potential changes in the relevant securities markets. In certain countries (for example, China) some exchanges may have holidays not found in the other exchanges.
How can this be? How can you have more futures contracts for gold than actual gold? Because you don't have to deliver a bar of gold when the contract matures. Many futures contracts settle on a "cash" basis – instead of physical delivery for the sale, the buyer receives the difference between the futures price (= the agreed-upon price) and the spot (= market) price.
form, number and at such place as such DTC Participant may reasonably request, in order that such notice, statement or communication may be transmitted by such DTC Participant, directly or indirectly, to such Beneficial owners. In addition, the Trust shall pay to each such DTC Participant a fair and reasonable amount as reimbursement for the expenses attendant to such transmittal, all subject to applicable statutory and regulatory requirements.

Here’s what’s Lisk all about: Most developers today rely on centralized giants, such as Google Play and the AppStore to put up their newly developed apps. These giants take much of the profits and attention from these apps, and Lisk believes all this should be going to the developers themselves. This is where its Javascript-based tech comes in. Lisk is incredibly exciting because it aims to offer a decentralized apps platform, one that actually favors the developers, and therefore gives them the bigger piece of the cake. Lisk was previously Crypti, and after proving itself on a community level, it was forked by Max Kordek and Oliver Beddows into Lisk, in 2016.


No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.
Currently, Bitcoin futures have very high margin requirements. The Cboe requires 40% of the notional amount for maintenance margin, the CME requires 43%. Your broker will likely require more than that. The culprit behind these high requirements is Bitcoin’s high volatility—until that calms down the exchanges will protect themselves by requiring a bunch of up-front money. If you don’t come up with the money for a margin call they want to close out your position without leaving a negative balance.
