The Custodian is responsible for safeguarding the Funds’ cash and securities, receiving and delivering securities, collecting the Funds’ interest and dividends, and performing certain administrative duties, all as directed by authorized persons. The Custodian is also responsible for the appointment and oversight of any sub-custodian banks and for providing reports regarding such sub-custodian banks and clearing agencies.
RD – Restricted default. ‘RD’ ratings indicate an issuer that in Fitch’s opinion has experienced an uncured payment default on a bond, loan or other material financial obligation but which has not entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure, and which has not otherwise ceased operating. This would include:
Exchanges simply take a fee to facilitate the orderbook where its clients (the counterparties) create and trade futures contract with each other. They also have to manage the system's risk so that traders don't get overleveraged or manipulate the market. Since counterparties are only putting margin down that is a % of the contract value, the exchange also has to handle liquidation procedures in case the value of the margin is exceeded by the loss on the notional market value of the contract. For instance, BitMEX offers 100x leverage, so if you want to enter a $10,000 position you need to put down $100 worth of bitcoin. If the price moves just 0.5% against your favor, BitMEX will take over your position and execute it into the market, so that the person on the other side of the contract can have someone else who pays for the profit. In the event that the liquidation doesn't get passed off to another trader, an Auto-Deleveraging/Termination can occur, or Socialize Loss in the contract builds (we will discuss these issues in more detail later).
In the event an order is cancelled, the Authorized Participant will be responsible for reimbursing the Fund for all costs associated with cancelling the order, including costs for repositioning the portfolio, provided the Authorized Participant shall not be responsible for such costs if the order was cancelled for reasons outside the Authorized Participant’s control or the Authorized Participant was not otherwise responsible or at fault for such cancellation. Upon written notice to the Distributor, such cancelled order may be resubmitted the following Business Day, with a newly constituted Portfolio Deposit or Fund Securities to reflect the next calculated NAV.

The proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there's currently no standard form of it. Some cryptocurrencies use a combined proof-of-work/proof-of-stake scheme.[18]

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

The tables below shows performance examples of an Ultra and UltraShort ProShares Fund that have investment objective to correspond to two times (2x) and two times the inverse (-2x) of, respectively, the daily performance of an index. In the charts below, areas shaded lighter represent those scenarios where a Fund will return the same or outperform (i.e., return more than) the index performance times the stated multiple in the Fund’s investment objective; conversely areas shaded darker represent those scenarios where the Fund will underperform (i.e., return less than) the index performance times the stated multiple in the Fund’s investment objective.
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.

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
Although forward currency contracts may be used by the Funds to try to manage currency exchange risks, unanticipated changes in currency exchange rates could result in poorer performance than if a Fund had not entered into these transactions. Even if the Advisor correctly predicts currency exchange rate movements, a hedge could be unsuccessful if changes in the value of a Fund’s position do not correspond to changes in the value of the currency in which its investments are denominated. This lack of correlation between a Fund’s forwards and currency positions may be caused by differences between the futures and currency markets.
The Funds may enter into swap agreements to gain exposure to an underlying asset without actually purchasing such asset, or to hedge a position including in circumstances in which direct investment is restricted for legal reasons or is otherwise impracticable. Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a day to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on a particular pre-determined investment or instrument. The gross return to be exchanged or “swapped” between the parties is calculated with respect to a “notional amount,” e.g., the return on or increase in value of a particular dollar amount invested in a “basket” of securities or an ETF representing a particular index or group of securities.
Elsewhere, here is the story of, which "has raised about $700 million and counting" by selling EOS tokens that it says "do not have any rights, uses, purpose, attributes, functionalities or features." is using the money to build "a new blockchain architecture designed to enable vertical and horizontal scaling of decentralized applications," as its white paper explains, and the white paper also includes a disclaimer in bold capitals:
Blockchain technology builds on the innovations of the blockchain and adopts it for many business, recreational and personal applications. Although initially associated with digital commodities like bitcoin and other cryptocurrencies, blockchain technology can be used to track tangible, intangible and digital assets and companies in all business sectors. Blockchain technology may, in the future, be used to support a wide array of business applications in many different industries and markets. It is an emerging technology that has the potential to redefine how records of value are transacted. Blockchain technology seeks to facilitate the process of recording transactions and tracking assets (e.g., cryptocurrency, contracts, information, etc.) through solving challenges of counterparty trust and alleviating the need for a central repository or ledger. It is designed to provide a transparent and secure process to transfer and digitally record information or property on a shared transaction database through a secure, decentralized, peer-to-peer distributed ledger.

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.
If you are serious about cryptocurrency trading, I strongly recommend finding a mastermind group that suits your skill level and budget so that you can improve your knowledge, expose yourself to less risk, and gain access to news and tips before they hit the mainstream market – this is where the real money is to be made. In my opinion, your best bet is to sign up to use the Notorious Bot as you get a ton of value not only from the bot but also from the Discord channel where you have access to veteran traders and analysts.
Distributions of investment income are generally taxable to shareholders as ordinary income. Taxes on distributions of capital gains are determined by how long a Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares. In general, a Fund will recognize long-term capital gain or loss on investments it has owned for more than one year, and short-term capital gain or loss on investments it has owned for one year or less. Tax rules can alter a Fund’s holding period in investments and thereby affect the tax treatment of gain or loss on such investments. Distributions of net capital gain – the excess of net long-term capital gain over net short-term capital losses, in each case determined with reference to any loss carryforwards – that are properly reported by the Fund as capital gain dividends (“Capital Gain Dividends”) will be taxable to shareholders as long-term capital gains includible in net capital gain and taxable to individuals at reduced rates. Distributions of net short-term capital gain (as reduced by any net long-term capital loss for the taxable year) will be taxable to shareholders as ordinary income.
Bitcoin and other cryptocurrencies have evolved from a playful experiment among technical experts to an established and growing branch of the global financial industry. This means that the times in which cryptocurrency traders and investors only concerned themselves with straightforward buying and selling are over. Derivatives are now entering the picture.
