Since you bought 68.4246 BTC, you want to short 68 BTC and lock in the USD value. You will have 0.4246 BTC left over, which will give you a slightly long bias. You can either fix this by only buying 68 BTC in step 1 or by giving yourself more short exposure by shorting 69 BTC. Remember that CryptoFacilities contracts are inverse (which allow locking in USD) and are denominated in BTC

Some exchanges offer trading on margin. When such an option is available, Bitcoiners are allowed to borrow funds from peer liquidity providers to carry out trades. The term "liquidity provider" refers to those who are ready to deposit their bitcoins and/or dollars with the exchange for use by others for a certain pre-fixed duration, rate, and amount. For example, say a Bitcoiner wants to buy 20 Bitcoins, anticipating that its price would rise in future and thus hopes to profit by selling them at a later date. If the person does not have sufficient funds to buy the 20 bitcoins, the margin facility allows him to borrow the amount required (20 X the price of bitcoins in USD) from a liquidity provider. When the Bitcoiner chooses to close the position, he needs to repay the amount borrowed plus the interest accrued during this time period. Remember that the amount accrued (loan + interest) needs to be reimbursed regardless of profit or loss at the time of settlement.

The Fund may invest in stocks of large-cap companies. Although returns on investments in large-cap companies are often perceived as being less volatile than the returns of companies with smaller market capitalizations, the return on large-cap securities could trail the returns on investments in smaller and mid-sized companies for a number of reasons. For example, large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies.
The use of swaps is a highly specialized activity which involves investment techniques and risks in addition to, and in some cases different from, those associated with ordinary portfolio securities transactions. The primary risks associated with the use of swap agreements are mispricing or improper valuation, imperfect correlation between movements in the notional amount and the price of the underlying investments, and the inability of the counterparties or clearing organization to perform. If a counterparty’s creditworthiness for an over-the-counter swap declines, the value of the swap would likely decline. Moreover, there is no guarantee that a Fund could eliminate its exposure under an outstanding swap agreement by entering into an offsetting swap agreement with the same or another party. In addition, a Fund may use a combination of swaps on an underlying index and swaps on an ETF that is designed to track the performance of that index. The performance of an ETF may not track the performance of its underlying index due to embedded costs
Under Delaware law, the Trust is not required to hold an annual shareholders meeting if the 1940 Act does not require such a meeting. Generally, there will not be annual meetings of Trust shareholders. Trust shareholders may remove Trustees from office by votes cast at a meeting of Trust shareholders or by written consent. If requested by shareholders of at least 10% of the outstanding Shares of the Trust, the Trust will call a meeting of Funds’ shareholders for the purpose of voting upon the question of removal of a Trustee of the Trust and will assist in communications with other Trust shareholders.
XBT futures is a cash-settled contract that settles to a single, tradeable auction price. In designing XBT futures, Cboe leveraged its significant product development expertise to design an instrument that allows participants to implement trading strategies in a manner to which they are accustomed. The single price settlement process gives participants the option of using XBT futures to hedge their exposure in underlying bitcoin or gain exposure to traded bitcoin prices without holding bitcoin.
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.
If this sounds confusing to you, then don't worry. In practice, these futures contracts are just like buying and selling spot market value. Just focus on the price of the contract and whether you are LONG or SHORT. If you're long and the futures price goes up, the BTC value of the contract goes up and you have bought an asset that is increasing in value.

On March 18, 2013, the Financial Crimes Enforcement Network (“FinCEN”) a bureau of the US Department of the Treasury, issued interpretive guidance relating to the application of the Bank Secrecy Act to distributing, exchanging and transmitting “virtual currencies.” More specifically, it determined that a user of virtual currencies (such as bitcoin) for its own account will not be considered a money service business (“MSB”) or be required to register, report and perform recordkeeping; however, an administrator or exchanger of virtual currency must be a registered money services business under FinCEN’s money transmitter regulations. As a result, Bitcoin Exchanges that deal with U.S. residents or otherwise fall under U.S. jurisdiction are required to obtain licenses and comply with FinCEN regulations. FinCEN released additional guidance clarifying that, under the facts presented, miners acting solely for their own benefit, software developers, hardware manufacturers, escrow service providers and investors in bitcoin would not be required to register with FinCEN on the basis of such activity alone, but that Bitcoin Exchanges, certain types of payment processors and convertible digital asset administrators would likely be required to register with FinCEN on the basis of the activities described in the October 2014 and August 2015 letters. FinCEN has also taken significant enforcement steps against companies alleged to have violated its regulations, including the assessment in July 2017 of a civil money penalty in excess of $110 million against BTC-e for alleged willful violation of U.S. anti-money laundering laws.

Below is a description of various types of money market instruments and other debt instruments that a Fund may utilize for investment purposes, as “cover” for other investment techniques such Fund employs, or for liquidity purposes. Other types of money market instruments and debt instruments may become available that are similar to those described below and in which the Funds also may invest consistent with their investment goals and policies. Each Fund may also invest in pooled investment vehicles that invest in, and themselves qualify as, money market instruments.

Make loans to other persons, except that the acquisition of bonds, debentures or other corporate debt securities and investment in government obligations, commercial paper, pass-through instruments, certificates of deposit, bankers’ acceptances and repurchase agreements and purchase and sale contracts and any similar instruments shall not be deemed to be the making of a loan, and except, further, that the Fund may lend its portfolio securities, provided that the lending of portfolio securities may be made only in accordance with applicable law and the guidelines set forth in the Prospectus and this SAI, as they may be amended from time to time.
There are so many hoops to jump through to set up for mining and each coin has its quirks. The power of your machine and graphix card and your power consumption are all important. My friend mined for 8month Eth and only made couple of hundred bucks by time you subtract power useage etc. He already had a powerful machine used in film industry for video graphix just sitting around so he thought he’d put it to use over that time for a laugh and see what happened. It took many hours messing around to set up and occassionally nursing it over that period. Of course he had to use his machine also occassionally which compromised the performance.
The Advisor, its principals, officers and employees (and members of their families) and affiliates may participate directly or indirectly as investors in the Advisor’s clients, such as the Funds. Thus the Advisor may recommend to clients the purchase or sale of securities in which it, or its officers, employees or related persons have a financial interest. The Advisor may give advice and take actions in the performance of its duties to its clients that differ from the advice given or the timing and nature of actions taken, with respect to other clients’ accounts and/or employees’ accounts that may invest in some of the same securities recommended to clients.
Each of the Funds may enter into repurchase agreements with financial institutions in pursuit of its investment objectives, as “cover” for the investment techniques it employs, or for liquidity purposes. Under a repurchase agreement, a Fund purchases a debt security and simultaneously agrees to sell the security back to the seller at a mutually agreed-upon future price and date, normally one day or a few days later. The resale price is greater than the purchase price, reflecting an agreed-upon market interest rate during the purchaser’s holding period. While the maturities of the underlying securities in repurchase transactions may be more than one year, the term of each repurchase agreement will always be less than one year. The Funds follow certain procedures designed to minimize the risks inherent in such agreements. These procedures include effecting repurchase transactions generally with major global financial institutions. The creditworthiness of each of the firms that is a party to a repurchase agreement with the Funds will be monitored by the Advisor. In addition, the value of the collateral underlying the repurchase agreement will always be at least equal to the repurchase price, including any accrued interest earned on the repurchase agreement. In the event of a default or bankruptcy by a selling financial institution, a Fund will seek to liquidate such collateral which could involve certain costs or delays and, to the extent that proceeds from any sale upon a default of the obligation to repurchase were less than the repurchase price, the Fund could suffer a loss. A Fund also may experience difficulties and incur certain costs in exercising its rights to the collateral and may lose the interest the Fund expected to receive under the repurchase agreement. Repurchase agreements usually are for short periods, such as one week or less, but may be longer. It is the current policy of the Funds not to invest in repurchase agreements that do not mature within seven days if any such investment, together with any other illiquid assets held by the Fund, amounts to more than 15% of the Fund’s total net assets. The investments of each of the Funds in repurchase agreements at times may be substantial when, in the view of the Advisor, liquidity, investment, regulatory, or other considerations so warrant.
In general, for purposes of the 90% gross income requirement described in subparagraph (a) above, income derived from a partnership will be treated as Qualifying Income only to the extent such income is attributable to items of income of the partnership which would be Qualifying Income if realized directly by the RIC.

The first timestamping scheme invented was the proof-of-work scheme. The most widely used proof-of-work schemes are based on SHA-256 and scrypt.[18] The latter now dominates over the world of cryptocurrencies, with at least 480 confirmed implementations.[37] Some other hashing algorithms that are used for proof-of-work include CryptoNight, Blake, SHA-3, and X11.
You might buy in to your Ethereum position at $1000, you set your sell position $1300. Your sell order could take days, weeks, months, years or till the end of time to be filled. Once it has been filled, you then take that profit and you roll it over in to a new buy over at, say, $1100. Choosing good targets for your buy and sell orders is crucial if you want to be a successful swing trader but overall swing trading cryptocurrency is pretty easy – set your orders and then just wait.
Inverse bitcoin contracts are usually denominated in USD terms. So if there's a contract value of $100 then each side -- LONG and SHORT -- puts down some portion of the contract value in margin. The contract is an agreement between traders to pay the other side an amount of bitcoin profit/loss as the price changes. Each contract has an expiration date, and some exchanges have periodic (daily or weekly) dates where the contract period's profits are "settled" even if the contract has not expired.
•   Active Management Risk — The performance of actively managed funds reflects, in part, the ability of ProShare Advisors to select investments and make investment decisions that are suited to achieving the Fund’s investment objective. ProShare Advisors’ judgments about the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by ProShares Advisors fail to produce the intended results, the Fund may not achieve its investment objective and could underperform other funds with a similar investment objective and/or strategies.
Shares may be redeemed only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor on any Business Day. The Trust will not redeem Shares in amounts less than Creation Units. Beneficial owners also may sell Shares in the secondary market, but must accumulate enough Shares to constitute a Creation Unit in order to have such Shares redeemed by the Trust. There can be no assurance, however, that there will be sufficient liquidity in the public trading market at any time to permit assembly of a Creation Unit of Shares. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of Shares to constitute a redeemable Creation Unit.

What’s important to consider as crypto evolves is to learn everything (or as much as possible) for yourself. Crypto coins all offer white papers to the public (though they’re not always easy to find). They’re for a scientific audience, but you’ve probably read worse if you have a university degree. Find them and read them. Don’t understand something, ask a question.
The Guidelines are maintained and implemented by ISS and are an extensive list of common proxy voting issues with recommended voting actions based on the overall goal of achieving maximum shareholder value and protection of shareholder interests. Generally, proxies are voted in accordance with the voting recommendations contained in the Guidelines. If necessary, the Advisor will be consulted by ISS on non-routine issues. Proxy issues identified in the Guidelines include but are not limited to:

Like all investments, investing in any of the Funds entails risks. The risk factors most likely to have a significant impact on a Fund’s portfolio are called “principal risks.” The principal risks of each Fund are described in the applicable Fund’s Summary Prospectus and additional information regarding certain of these principal risks, as well as information related to other potential risks to which a particular Fund may be subjected, is provided below. Some risks apply to all of the Funds, while others are specific to the investment strategies of certain Funds, as indicated below. Each Fund may be subject to other risks in addition to those identified as principal risks.
The consideration for purchase of a creation unit of a Fund may, at the discretion of the Advisor, consist of the in-kind deposit of a designated portfolio of securities (“Deposit Securities”) constituting a representation of the index for the Fund, the Balancing Amount, and the appropriate Transaction Fee (collectively, the “Portfolio Deposit”). The “Balancing Amount” will be the amount equal to the differential, if any, between the total aggregate market value of the Deposit Securities (or in the case of redemptions, the total aggregate market value of the Fund Securities as defined below) and the NAV of the Creation Units being purchased and will be paid to, or received from, the Trust after the NAV has been calculated. The Advisor may restrict purchases of Creation Units to be on an in-kind basis at any time and without prior notice, in all cases at the Advisor’s discretion.
The CME Bitcoin futures contracts will be cash-settled, meaning that you will receive USD on the expiration date if your speculation was successful and you have not sold the derivative before the expiration date. You will not receive Bitcoin – that would be a physical settlement, even though Bitcoin is not a physical asset. This is a crucial difference because it enables traders to trade in Bitcoin futures without having a cryptocurrency wallet. Every transaction is done in USD.Thus, it is easy for mainstream traders to take part in this market.
