Floating and variable rate notes generally are unsecured obligations issued by financial institutions and other entities. They typically have a stated maturity of more than one year and an interest rate that changes either at specific intervals or whenever a benchmark rate changes. The effective maturity of each floating or variable rate note in a Fund’s portfolio will be based on these periodic adjustments. The interest rate adjustments are designed to help stabilize the note’s price. While this feature helps protect against a decline in the note’s market price when interest rates rise, it lowers a Fund’s income when interest rates fall. Of course, a Fund’s income from its floating and variable rate investments also may increase if interest rates rise.
Changes in the Bitcoin Network could have an adverse effect on the operation and value of bitcoin, which could have an adverse effect on the value of Bitcoin Futures Contracts and the value of Fund Shares. 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.” Such changes may influence
Furthermore, each Fund, except the Matching ProShares Funds, the Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the CDS Short North American HY Credit ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, the Bitcoin Futures/Equity Strategy ETF has an investment objective to match the performance, a multiple (2x or 3x), the inverse (-1x) or a multiple of the inverse (-2x or -3x) of the performance of a benchmark on a single day. A “single day” is measured from the time the Fund calculates its NAV to the time of the Fund’s next NAV calculation. These Funds are subject to the correlation risks described above. In addition, while a close correlation of any Fund to its benchmark may be achieved on any single day, over time, the cumulative percentage increase or decrease in the NAV of the shares of a Fund may diverge, in some cases significantly, from the cumulative percentage decrease or increase in the benchmark due to a compounding effect as further described in the Prospectus and below.
The moment you look at the amount of support Tron has been receiving lately, you immediately realize it’s not just yet another blockchain-based platform. Tron’s technology aims to deploy world’s largest FREE content entertainment system. The platform allows anyone to store and own data, and to freely publish their content. Its app “Peiwo” already gathers 10 million enthusiasts and is on the road to become the world’s first TRON-compatible entertainment app. This technology revolves around the following ideology:  All contributions on the network should be of equal quantitative value, the Internet should be decentralized, and data creators should have the absolute ownership of the data. It’s important to realise though that Tron has been pushed like hell by an ambitious marketing department… I have not yet decided if this is a cryptocurrency which will survive but, for a one year hold, it seems a safe bet.
An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017.[49] Popular favorites of cryptocurrency miners such as Nvidia’s GTX 1060 and GTX 1070 graphics cards, as well as AMD’s RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[50] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.[51]
The truth is that bitcoin is the hottest trading market right now, hotter than stock trading, oil trading, gold trading and any other market at this point. The reason people believe this is going to continue to be a hot market is because blockchain technology which is what allows transactions to happen without a central exchange. Here is another strategy on how to draw trend lines with fractals.
Special rules would apply if a Fund were a qualified investment entity (“QIE”) because it is either a “U.S. real property holding corporation” (“USRPHC”) or would be a USRPHC but for the operation of certain exceptions to the definition of USRPIs described below. Very generally, a USRPHC is a domestic corporation that holds USRPIs the fair market value of which equals or exceeds 50% of the sum of the fair market values of the corporation’s USRPIs, interests in real property located outside the United States, and other trade or business assets. USRPIs generally are defined as any interest in U.S. real property and any interest (other than solely as a creditor) in a USRPHC or, very generally, an entity that has been a USRPHC in the last five years. A Fund that holds, directly or indirectly, significant interests in REITs may be a USRPHC. Interests in domestically controlled QIEs, including REITs and RICs that are QIEs, not-greater-than-10% interests in publicly traded classes of stock in REITs and not-greater-than-5% interests in publicly traded classes of stock in RICs generally are not USRPIs, but these exceptions do not apply for purposes of determining whether a Fund is a QIE.

through direct investments/short positions in the securities and/or through investments with similar economic characteristics. For the purposes of each such investment policy, “assets” includes a Fund’s net assets, as well as amounts borrowed for investment purposes, if any. In addition, for purposes of such an investment policy, “assets” includes not only the amount of a Fund’s net assets attributable to investments providing direct investment exposure to the type of investments suggested by its name (e.g., the value of stocks, or the value of derivative instruments such as futures, options or options on futures), but also cash and cash equivalents that are segregated on the Fund’s books and records or being used as collateral, as required by applicable regulatory guidance, or otherwise available to cover such investment exposure. The Board has adopted a policy to provide investors with at least 60 days’ notice prior to changes in a Fund’s name policy.
These days, all of the BTC/USD contracts trading at active futures markets are inverse, as mentioned in the beginning of this guide. The only differences between the exchanges is how they trigger liquidations and the procedure for handling margin calls. They all use Bitcoin as the currency, of course, and you can use the table below for a basic feature comparison:

Each Fund intends to invest to a significant extent in bitcoin futures contracts. Each Fund expects to gain exposure to bitcoin futures contracts by investing a portion of its assets in a wholly-owned subsidiary of such Fund organized under the laws of the Cayman Islands (each, a “Subsidiary”). Each Subsidiary is advised by ProShare Advisors, the Fund’s investment advisor. Unlike the Fund, a Subsidiary is not an investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). Each Fund’s investment in the Subsidiary is intended to provide the Fund with exposure to bitcoin futures contracts in accordance with applicable rules and regulations. Each Fund will invest up to 25% of its total assets in its corresponding Subsidiary. Except as otherwise noted, references to a Fund’s investment strategies and risks include the investment strategies and risks of its underlying Subsidiary.

As for why you should buy a put option instead of the asset itself, the answer is simple. By buying the asset itself, you can never profit from falling prices. With put options you can, simply because their value rises as the price of the underlying stock is falling. In addition to this feature, they offer the same kind of potential for leverage that calls options do, as described above. The price of put options is calculated in a similar manner, but with the important difference being that the intrinsic value is calculated as a predetermined price of the option minus the current market price of the asset – not the other way round as is the case for call options.
