Jordan Kelley, founder of Robocoin, launched the first bitcoin ATM in the United States on 20 February 2014. The kiosk installed in Austin, Texas is similar to bank ATMs but has scanners to read government-issued identification such as a driver's license or a passport to confirm users' identities.[60] By September 2017, 1,574 bitcoin ATMs had been installed around the world with an average fee of 9.05%. An average of 3 bitcoin ATMs were being installed per day in September 2017.[61]
Disctric0x is a network of decentralized communities and marketplaces, and where each ‘district’ is a decentralized entity on the district0x Network. In other words, District0x allows anyone to create a network of communities (or organizations) with a focus on governance, cooperation and decision making being decentralized. District0x is an open-source software project, and as such, it does not seek to gain profit, but rather focuses all of its attention towards building software that enables development and governance of marketplaces that are powered by the community.
and other factors. Thus, to the extent a Fund invests in swaps that use an ETF as the reference asset, that Fund may be subject to greater correlation risk and may not achieve as high a degree of correlation with its index as it would if the Fund used only swaps on the underlying index. The Advisor, under the supervision of the Board of Trustees, is responsible for determining and monitoring the liquidity of the Funds’ transactions in swap agreements.
Additions such as Zerocoin have been suggested, which would allow for true anonymity.[54][55][56] In recent years, anonymizing technologies like zero-knowledge proofs and ring signatures have been employed in the cryptocurrencies Zcash and Monero, respectively. Cryptocurrency anonymizing implementations such as Cloakcoin, Dash, and PIVX use built in mixing services, also known as tumblers.[57]

The Fund may invest in stocks of small- and mid- cap companies. The risk of equity investing may be particularly acute for securities of issuers with smaller market capitalizations. Small- and mid-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Small- and mid-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Further, stocks of small- and mid-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies. In addition, small- and mid-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small- and mid- cap security prices.
The Bitcoin protocol was built using open source software by a small group of individuals who developed what is known today as “Bitcoin Core.” The open source nature of the Bitcoin protocol permits any developer to review the underlying code and suggest changes to it via “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” (as described herein). The Bitcoin Network has already experienced two major forks after developers attempted to increase transaction capacity. Blocks mined on these new “forked” networks now diverge from blocks mined on the original Bitcoin Network maintained by Bitcoin Core, resulting in the creation of two new blockchains whose digital assets are referred to as “bitcoin cash.” and “bitcoin gold.” Bitcoin, bitcoin cash and bitcoin gold now operate as separate, independent networks. Multiple BIPs still exist, many of which are aimed at increasing the transaction capacity of the Bitcoin Network, and it is possible that one or more of these BIPs could result in further network “forks.” Such changes may
The Bitcoin Network and bitcoin, as an asset, currently hold a “first-to-market” advantage, often referred to as a “network effect,” over other digital assets. This first-to-market advantage has resulted in the Bitcoin Network evolving into the most well developed network of any digital asset. The Bitcoin Network enjoys the largest user base of any digital asset and, more importantly, the largest combined mining power in use to secure the Bitcoin Blockchain. Having a large mining network enhances user confidence regarding the security of the Bitcoin Blockchain and long-term stability of the Bitcoin Network. Despite the marked network effect advantage of the Bitcoin Network over other digital assets, it is possible that real or perceived shortcomings in the Bitcoin Network, technological, regulatory or other developments could result in a decline in popularity and acceptance of bitcoin and the Bitcoin Network.

Margin-trading is what provides the real reward and potential in daytrading bitcoin. You will be able to access the leverage to profit well from relatively small moves in BTC/USD price. High risk, high reward, high potential for loss. However, you need not use Futures only to speculate, hedging on lower leverage is also a great use case for Bitcoin derivatives if you just want to defend your coins. 

Anyone interested in buying bitcoins needs to deposit funds in U.S. dollars, euros, or another currency supported by the exchange. The popular methods of transferring money to the currency exchanges are through bank wire transfers, credit cards, or liberty reserves. One of the pre-requisites here is to have a digital wallet to hold bitcoins. Bitcoins bought can be stored in a digital wallet, device, or paper wallet, depending on the buyer’s preference. For sellers, the fait currency for which the Bitcoins have been sold needs to be withdrawn from the exchange and sent to a bank. One issue that can arise is if the exchange has liquidity concerns at a particular point in time; such situations can delay withdrawal and transfer of funds into a bank account. (For more, see: A Look At The Most Popular Bitcoin Exchanges.)
The Global Listed Private Equity ETF and the Short Term USD Emerging Markets Bond ETF each pay ProShare Advisors a fee at an annualized rate based on its average daily net assets of 0.50%. The Inflation Expectations ETF pays ProShare Advisors a fee at an annualized rate based on its average daily net assets of 0.55%. The CDS Short North American HY Credit ETF pays ProShare Advisors a fee at an annualized rate based on its average daily net assets of 0.65%. ProShare Advisors manages the investment and the reinvestment of the assets of each of the Funds in accordance with the investment objectives, policies, and limitations of the Fund, subject to the general supervision and control of the Trustees and the Officers of the Trust. ProShare Advisors bears all costs associated with providing these advisory services. Except for the Morningstar Alternatives Solution ETF, ProShare Advisors has contractually agreed to waive investment advisory and management services fees and to reimburse other expenses (exclusive of transaction costs,
that receive different proportions of the interest and principal distributions from a pool of mortgage assets. The Funds will only invest in SMBS whose mortgage assets are U.S. government obligations. A common type of SMBS will be structured so that one class receives some of the interest and most of the principal from the mortgage assets, while the other class receives most of the interest and the remainder of the principal. If the underlying mortgage assets experience greater than anticipated prepayments of principal, each Fund may fail to fully recoup its initial investment in these securities. The market value of any class that consists primarily or entirely of principal payments generally is unusually volatile in response to changes in interest rates.
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.
Bitcoin is maintained on the decentralized, open source protocol of the peer-to-peer bitcoin computer network (the “Bitcoin Network”). No single entity owns or operates the Bitcoin Network. The infrastructure of the Bitcoin Network is collectively maintained by a decentralized user base. The Bitcoin Network is accessed through software, and software governs bitcoin’s creation, movement, and ownership. The value of bitcoin is determined in great part by the supply of (which is limited), and demand for, bitcoin in the global exchange markets for the trading of bitcoin (individually, “Bitcoin Exchanges” and collectively, the “Bitcoin Exchange Market”), market expectations for the adoption of bitcoin and the volume of private user-to-user transactions.
R-1 (middle) – Short term debt rated “R-1 (middle)” is of superior credit quality and, in most cases, ratings in this category differ from “R-1 (high)” credits to only a small degree. Given the extremely tough definition which DBRS has for the “R-1 (high)” category (which few companies are able to achieve), entities rated “R-1 (middle)” are also considered strong credits which typically exemplify above average strength in key areas of consideration for debt protection.

Each Fund, except for the S&P 500 Dividend Aristocrats ETF, the S&P MidCap 400 Dividend Aristocrats ETF, the Russell 2000 Dividend Growers ETF, the MSCI EAFE Dividend Growers ETF, the MSCI Europe Dividend Growers ETF, the MSCI Emerging Markets Dividend Growers ETF, the DJ Brookfield Global Infrastructure ETF, the Equities for Rising Rates ETF, the S&P 500 Ex-Energy ETF, the S&P 500 Ex-Financials ETF, the S&P 500 Ex-Health Care ETF, the S&P 500 Ex-Technology ETF, the High Yield—Interest Rate Hedged, the Investment Grade—Interest Rate Hedged and the Short Term USD Emerging Markets Bond ETF, is a “non-diversified” series of the Trust. A Fund’s classification as a “non-diversified” investment company means that the proportion of the Fund’s assets that may be invested in the securities of a single issuer is not limited by the 1940 Act. Notwithstanding each Fund’s status as a “non-diversified” investment company under the 1940 Act, each Fund intends to qualify as a RIC accorded special tax treatment under the Code, which imposes its own diversification requirements on these Funds that are less restrictive than the requirements applicable to the “diversified” investment companies under the 1940 Act. A Fund’s ability to pursue its investment strategy may be limited by that Fund’s intention to qualify as a RIC and its strategy may bear adversely on its ability to so qualify. For more details, see “Taxation” below. With respect to a “non-diversified” Fund, a relatively high percentage of such a Fund’s assets may be invested in the securities of a limited number of issuers, primarily within the same economic sector. That Fund’s portfolio securities, therefore, may be more susceptible to any single economic, political, or regulatory occurrence than the portfolio securities of a more diversified investment company.
  •   Inverse Correlation Risk — 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.
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.
The biggest problem of the Blockchain is its reliance on miners. This is exactly why the cryptocurrency called IOTA (the Internet of Thigs Application) was created in 2016. IOTA also battles increasing transaction fees and network scalability. IOTA’s blockchain is called Tangle. It is a blockchain with no blocks and no chains. In this system, the users themselves are responsible for validating transactions. This means there’s no need for approval from miners; so users enjoy a fee-free transaction and an increased process speed.
•   Tax Risk — In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategies will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund can make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.
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.
The Morningstar Alternatives Solution ETF pays ProShare Advisors a fee at an annualized rate based on its average daily net assets of 0.07%. ProShare Advisors has entered into an Advisory and Management Services Fee Waiver Agreement that waives this investment advisory fee for the Morningstar Alternatives Solution ETF through at least October 31, 2018. Prior to this date, ProShare Advisors may not terminate the arrangement without the approval of the Board.
“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.”
influence the price of Bitcoin and Bitcoin Instruments. In particular, it is possible that the price of the Bitcoin Instruments 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 CFE and CME have announced different protocols for addressing forks.
The foregoing discussion is primarily a summary of certain U.S. federal income tax consequences of investing in a Fund based on the law in effect as of the date of this SAI. The discussion does not address in detail special tax rules applicable to certain classes of investors, such as, among others, IRAs and other retirement plans, tax-exempt entities, foreign investors, insurance companies, banks and other financial institutions, and investors making in-kind contributions to a Fund. Such shareholders may be subject to U.S. tax rules that differ significantly from those summarized above. You should consult your tax advisor for more information about your own tax situation, including possible other federal, state, local and, where applicable, foreign tax consequences of investing in a Fund.
CCC/CC/C – Very highly speculative credit quality. In danger of defaulting on financial obligations. There is little difference between these three categories, although CC and C ratings are normally applied to obligations that are seen as highly likely to default, or subordinated to obligations rated in the CCC to B range. Obligations in respect of which default has not technically taken place but is considered inevitable may be rated in the C category.
According to PricewaterhouseCoopers, four of the 10 biggest proposed initial coin offerings have used Switzerland as a base, where they are frequently registered as non-profit foundations. The Swiss regulatory agency FINMA stated that it would take a “balanced approach“ to ICO projects and would allow “legitimate innovators to navigate the regulatory landscape and so launch their projects in a way consistent with national laws protecting investors and the integrity of the financial system.” In response to numerous requests by industry representatives, a legislative ICO working group began to issue legal guidelines in 2018, which are intended to remove uncertainty from cryptocurrency offerings and to establish sustainable business practices.[65]

Localbitcoins is the portal that exchanges trades between person to person where you interact with the seller directly. On this platform, people from different countries can exchange their local currency to bitcoins. The site is suggested for casual traders seeking more privacy. The site uses an escrow system and the transfer of bitcoin is made after funds are received in the sellers account. Registering, buying and selling is completely free on localbitcoins while local bitcoin users who create advertisements charges 1% fee for every completed trade.
In September 2015, the establishment of the peer-reviewed academic journal Ledger (ISSN 2379-5980) was announced. It covers studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh.[114][115] The journal encourages authors to digitally sign a file hash of submitted papers, which will then be timestamped into the bitcoin blockchain. Authors are also asked to include a personal bitcoin address in the first page of their papers.[116][117]
Fundamental securities analysis is not used by ProShare Advisors in seeking to correlate a Matching Fund’s investment returns with its index. Rather, ProShare Advisors primarily uses a passive or mathematical approach to determine the investments a Matching Fund makes and techniques it employs. While ProShare Advisors attempts to minimize any “tracking error,” certain factors tend to cause a Matching Fund’s investment results to vary from a perfect correlation to its index, as applicable. See “Special Considerations” below for additional details.

  •   Developmental risk. Blockchain technology is not a product or service within an individually attributable revenue stream. Blockchain technology may never develop optimized transactional processes that lead to realized economic returns for any company in which the Fund invests. Blockchain Companies that are developing applications of blockchain technology applications may not in fact do so or may not be able to capitalize on those blockchain technologies. The development of new or competing platforms may cause consumers and investors to use alternatives to blockchains.
Having said that, bitcoin price action remains fraught with wild and inexplicable gaps, like a $400 drop and rise in an hour in the late hours of July 30, according to Bloomberg.  This particular trade, and unwind seems to have affected bitcoin pricing globally and likely impacted trading of the U.S. listed contracts as well.  Volumes and open interest seemed to have increased around the time of this large trade unwind.  It could be a coincidence, though I suspect that some smart traders, aware of the situation, put short trades on in these future contracts to take advantage of the forced unwind.

It’s reasonable to assume that a product named a future is attempting to predict the future. For Bitcoin futures, this is definitely not what they deliver. The core utility of the futures markets is not predicting the future prices of their product but rather the secure delivery of a product at a known price, quality, and date. If there’s product seasonality (e.g., specific harvest times) or foreseeable shortages/abundances then future’s prices may reflect that but neither of these factors applies to Bitcoin.
