If a shareholder is eligible for the benefits of a tax treaty, any effectively connected income or gain will generally be subject to U.S. federal income tax on a net basis only if it is also attributable to a permanent establishment maintained by the shareholder in the United States. More generally, foreign shareholders who are residents in a country with an income tax treaty with the United States may obtain different tax results than those described herein, and are urged to consult their tax advisors.

Hey Jhon, I haven’t found a crypto yet that is really related to my hobbies – Crossfit and backpacking – but I would actually advise steering clear of investing in things linked too closely to what you’re passionate about; whilst insider knowledge of an industry is really valuable, it’s important to trade without emotion and if your trading a coin that is linked to a great love of yours, that becomes harder.
Crypto derivatives were naturally discovered as an interesting addition to cryptocurrency exchanges first – probably as individual contracts between interested investors on these exchanges. Nowadays, there are already a couple of exchanges that offer crypto derivatives trading as a standard feature: BitMEX is the current market leader, according to The Merkle News; others are OKCoin, Crypto Facilities, Coinpit, and Deribit, as well as LedgerX (the first regulated cryptocurrency exchange in the US).
Transaction fees payable to the Trust are imposed to compensate the Trust for the transfer and other transaction costs of a Fund associated with the issuance and redemption of Creation Units of Shares. A fixed Transaction Fee is applicable to each creation or redemption transaction, regardless of the number of Creation Units purchased or redeemed. In addition, a variable Transaction Fee equal to a percentage of the value of each Creation Unit purchased or redeemed may be applicable to a creation or redemption transaction. Purchasers of Creation Units of the Matching and Ultra ProShares Funds for cash may also be required to pay an additional charge to compensate the relevant Fund for brokerage, market impact or other expenses. Where the Trust permits an in-kind purchaser to substitute cash in lieu of depositing a portion of the Deposit Securities, the purchaser will be assessed an additional charge for cash purchases. The maximum Transaction Fee on purchases and redemptions will be 2.00% of the NAV of any Creation Unit, except that for the High Yield—Interest Rate Hedged, the Investment Grade—Interest Rate Hedged and the Short Term USD Emerging Markets Bond ETF, a Transaction Fee up to 3.00% will be charged on the cash used in lieu of depositing all or a portion of the Deposit Securities or the cash portion of any redemption transaction. The Transaction Fees charged to each Fund are presented in the Authorized Participant Handbook.
•   Compounding Risk — In the course of managing the Fund’s investments, ProShare Advisors will need to periodically adjust the Fund’s holdings in order to maintain investment exposure approximately equivalent to the Fund’s assets. This process entails obtaining additional inverse exposure as the Fund experiences gains, and reducing inverse exposure as the Fund experiences losses. The higher the volatility of the bitcoin futures contracts in which the Fund invests, the more such rebalancing can adversely affect the Fund’s performance.

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.

In certain circumstances, the securities delivery cycles currently practicable for transferring portfolio securities to redeeming investors, coupled with foreign market holiday schedules, will require a delivery process longer than seven calendar days. The holidays applicable to various countries during such periods are listed below, as are instances where more than seven days will be needed to deliver redemption proceeds. Although certain holidays may occur on different dates in subsequent years, the number of days required to deliver redemption proceeds in any given year is not expected to exceed the maximum number of days listed below for each Fund. The proclamation of new holidays, the treatment by market participants of certain days as “informal holidays” (e.g., days on which no or limited securities transactions occur, as a result of substantially shortened trading hours), the elimination of existing holidays, or changes in local securities delivery practices, could affect the information set forth herein.
Litecoin (LTC) is similar to Bitcoin in many of its characteristics and is also one of the more veteran cryptocurrencies out there. However, there are two main differences between Litecoin and Bitcoin: Speed and amount. While it takes 10 minutes to create a Bitcoin block, Litecoin demands roughly 2.5 minutes to create a block – meaning 4 times the speed. Moreover, Litecoin attracts many users, as it can produce 4 times the quantity of Bitcoin! However, as Litecoin uses highly complex cryptography, often mining it is more complicated than other cryptocurrencies.
These are NOT linked to or related in any way, to the futures contracts that trade on the CME or CBOE.  Not every article I have read makes this clear.  So the bright side of this story is that the contracts listed and traded on U.S. exchanges were not involved.  That is encouraging from both a regulatory aspect and for the future potential growth of cryptocurrency linked products in the U.S.
Only invest what you can lose. During the recent crash in January 2018, hobby-investors got burned. Reports of frustration and losses came at the cost of broken monitors, smashed laptops, and heavy monetary losses. While the rules are in more particular order of importance, it’s safe to assume that this is the most important rule, the rule to rule the rules. As soon as your money is converted into cryptocurrency, consider it lost forever. There is absolutely no guarantee you can get it back. Losses don’t simply come from dips in the market; extraordinary factors such as hacks, bugs, and government regulation can mean you’ll never see any of your money again. If you are investing money you can’t afford to lose, you need to take a step back and re-evaluate your current financial situation, because what you’re about to do is an act of desperation. This includes: using credit cards, taking out mortgages, applying for loans, or selling everything and traveling the world (as glamorous as that sounds).
A U.S. person, including a Fund, who owns (directly or indirectly) 10% or more of the total combined voting power of all classes of stock of a foreign corporation is a “U.S. Shareholder” for purposes of the CFC provisions of the Code. A CFC is a foreign corporation that, on any day of its taxable year, is owned (directly, indirectly, or constructively) more than 50% (measured by voting power or value) by U.S. Shareholders. Because of its investment in its Subsidiary, each Parent Fund is a U.S. Shareholder in a CFC. As a U.S. Shareholder, each Parent Fund is required to include in gross income for U.S. federal income tax purposes for each taxable year of the Fund its pro rata share of its CFC’s “subpart F income” for the CFC’s taxable year ending within the Fund’s taxable year whether or not such income is actually distributed by the CFC, provided that the foreign corporation has been a CFC for at least 30 uninterrupted days in its taxable year. Subpart F income generally includes interest, OID, dividends, net gains from the disposition of stocks or securities, net gains from transactions (including futures, forward, and similar transactions) in commodities, receipts with respect to securities loans, and net payments received with respect to equity swaps and similar derivatives. Subpart F income is treated as ordinary income, regardless of the character of the CFC’s underlying income. Net losses incurred by a CFC during a tax year do not flow through to an investing Fund and thus will not be available to offset income or capital gain generated from that Fund’s other investments. In addition, net losses incurred by a CFC during a tax year generally cannot be carried forward by the CFC to offset gains realized by it in subsequent taxable years. To the extent each Parent Fund invests in its Subsidiary and recognizes subpart F income in excess of actual cash distributions from such the Subsidiary, if any, it may be required to sell assets (including when it is not advantageous to do so) to generate the cash necessary to distribute as dividends to its shareholders all of its income and gains and therefore to eliminate any tax liability at the Fund level. Subpart F income also includes the excess of gains over losses from transactions (including futures, forward and other similar transactions) in commodities.

In traditional financial markets, derivatives are used as speculation objects as well as insurance against losses. The latter is known as hedging. One popular variety of derivatives used for hedging are called futures. A future is a contract between two parties in which one party agrees to pay the other a predetermined amount of money for an underlying asset at a specific point in time.
