•   Futures Position Limit Risk — Limits on the amount of futures any one entity can hold may negatively impact the Fund’s ability to meet its investment objective if such limits are reached and exceptions to such limits are not granted. Currently the position limits for bitcoin futures contracts are much lower than they are for most other futures contracts.
It can often be confusing to traders who are using multiple futures exchanges with different contract types -- inverse and qunato, dailies or quarterlies, 5x or 100x -- so people wonder: what should I trade? Well, it depends on what your goals are. If you are trying to do a little hedge for a medium term, you would want to use a quarterlies expiration contract instead, because otherwise you'd have to reopen shorter-term contracts after they expire and settle. 
Mathematically, to regain a 50% loss you need the price to rise 100% (double) so don’t let yourself get there. Psychologically, you force yourself to trade to make up for the losses, and under pressure, you won’t make the best decisions. Cut losses early and re-evaluate your reasons for the trade, go back in later on, at a lower price if needed. Don’t take profits early, wait for a drop – this is a good enough place to close the trade
As of May 2018, over 1,800 cryptocurrency specifications existed.[29] Within a cryptocurrency system, the safety, integrity and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners: who use their computers to help validate and timestamp transactions, adding them to the ledger in accordance with a particular timestamping scheme.[16]
Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes[95] and economic bubbles,[96] such as housing market bubbles.[97] Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were "nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it", and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999).[98]
•   If a Fund qualifies for treatment as a regulated investment company, it is not subject to federal income tax on net investment income and net realized capital gains that the Fund timely distributes to its shareholders. If a Fund were to fail to so qualify, and were ineligible to or otherwise did not cure such failure, its taxable income and gains would be subject to tax at the Fund level, and distributions from earnings and profits would be taxable to shareholders as ordinary income.

Each Fund may be required to withhold federal income tax (“backup withholding”) from dividends and capital gains distributions paid to shareholders. Federal tax will be withheld if (1) the shareholder fails to furnish the Fund with the shareholder’s correct taxpayer identification number or social security number, (2) the IRS notifies the shareholder or the Fund that the shareholder has failed to report properly certain interest and dividend income to the IRS and to respond to notices to that effect, or (3) when required to do so, the shareholder fails to certify to the Fund that he or she is not subject to backup withholding. The backup withholding rate is 28%. Any amounts withheld under the backup withholding rules may be credited against the shareholder’s federal income tax liability.
The only way that new Bitcoin can be created is through a process called “mining.” Bitcoin mining occurs when users process transactional data into “blocks” and then add them to the blockchain. As payment for this service, miners are awarded specific amounts of new Bitcoin. Upon its launch, the maximum supply of Bitcoin was predetermined to be 21 million.
Most swap agreements entered into by a Fund (but generally not CDS) calculate and settle the obligations of the parties to the agreement on a “net basis” with a single payment. Consequently, a Fund’s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”). Other swap agreements, such as CDS, may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of the reference entity.

For example, you can enter a Bitcoin futures contract with Mortimer Duke saying that you will sell him 1 BTC on March 30, 2018, for the price of 5,000 USD per BTC. (In the actual CME futures contracts, the limit for one contract is 5 BTC, but we will stick with 1 BTC now for the purposes of easy explanation.) You enter into this contract on an exchange like CME.
Almost every crypto-list today starts off with the king – Bitcoin! Satoshi Nakamoto created Bitcoin a long time ago, and it was the first cryptocurrency to step blinking into the bright light of the world! Bitcoin has surpassed all expecatations and continues to grow in value and popularity – despite recent setbacks and a lot of FUD from trolls and haters (read: traditional banks) online.  Will Bitcoin continue to increase in value in 2018? Recent trends say: Yes! In my opinion, any cryptocurrency portfolio should hold some Bitcoin.
I have worked with the CME in the past on product development (specifically CDS futures) and from my experience, they would not have missed anything this simple.  In fact, while I am not a huge fan of the concept of Bitcoin futures, as currently implemented, I do not expect any errors in the operation of the CME or CBOE futures contract.  I am sure that regulators will be questioning them on the back of the OKEX, as they should, and I am also quite positive the exchanges here will pass with flying colors.
This means simply that you put down 1 bitcoin and you can trade 20 on OKCoin, or 100 bitcoin on BitMEX. The multiple refers to the initial margin you need to open the nominal position value. You simply set the margin aside as collateral, and if the position goes against you, the collateral will be used to exit your position into a liquidation, or margin call.
Each Fund intends to invest in bitcoin futures contracts. The Funds will not invest directly in bitcoin and are not benchmarked to the current price of bitcoin. The value of the bitcoin futures contracts is generally based on the expected value of bitcoin at a future point in time, specifically, the expiration date of the bitcoin futures contracts. Other factors, such as cost of mining, storing and securing bitcoin may affect the value of bitcoin futures. A change in the price of bitcoin today (sometimes referred to as the “spot” price) will not necessarily result in a corresponding movement in the price of the bitcoin futures contracts since the price of the bitcoin futures contracts is based on expectations of the price of bitcoin at a future point in time. Additionally, there is no one centralized source for pricing bitcoin and pricing from one bitcoin exchange to the next can vary widely. Additionally, each Fund has the ability to invest in, or take a short position in, bitcoin futures contracts offered by CFE or CME, each of which uses a different exchange, or exchanges, to determine the value of bitcoin, which may lead to material differences in the value of the bitcoin futures contracts offered by CFE and CME. As a result, each Fund should be expected to perform very differently from the performance of the spot price of bitcoin (or the inverse of such performance) over all periods of time.
Each Fund may buy and write (sell) options for the purpose of realizing its investment objective. By buying a call option, a Fund has the right, in return for a premium paid during the term of the option, to buy the asset underlying the option at the exercise price. By writing a call option a Fund becomes obligated during the term of the option to sell the asset underlying the option at the exercise price if the option is exercised. By buying a put option, a Fund has the right, in return for a premium paid during the term of the option, to sell the asset underlying the option at the exercise price. By writing a put option, a Fund becomes obligated during the term of

The regulation of bitcoin, digital assets and related products and services continues to evolve. The inconsistent and sometimes conflicting regulatory landscape may make it more difficult for bitcoin businesses to provide services, which may impede the growth of the bitcoin economy and have an adverse effect on consumer adoption of bitcoin. There is a possibility of future regulatory change altering, perhaps to a material extent, the nature of an investment in the Funds or the ability of the Funds to continue to operate. Additionally, to the extent that bitcoin itself is determined to be a security, commodity future or other regulated asset, or to the extent that a United States or foreign government or quasi-governmental agency exerts regulatory authority over the Bitcoin Network, bitcoin trading or ownership in bitcoin, the price of bitcoin and the value of the Bitcoin Instruments may be adversely affected, which may have an adverse effect on the value of your investment in the Funds. In sum, bitcoin regulation takes many different forms and will, therefore, impact bitcoin and its usage in a variety of manners. The European Union has recently agreed to rules designed to reduce anonymity of bitcoin transactions, which may impact the supply and demand for bitcoin and bitcoin futures contracts.
In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income (“UBTI”) to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax on UBTI, thereby potentially requiring such an entity that is allocated excess inclusion income, and otherwise might not be required to file a tax return, to file a return and pay tax on such income, and (iii) in the case of a foreign shareholder (defined below), will not qualify for any reduction in U.S. federal withholding tax. A shareholder will be subject to income tax on such inclusions without reference to any exemption therefrom otherwise available under the Code.

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.

You’ll find that different exchanges cater to different markets. Today, most countries have at least one cryptocurrency exchange specializing in their own currency. There are exchanges that can accept New Zealand Dollars in exchange for bitcoin, for example. Other exchanges are known for certain pairs. Bithumb, for example, has particularly strong liquidity in the ETH/KRW (South Korean Won) pair at the moment (and it’s easily the most popular cryptocurrency exchange in Korea).

The tax treatment of certain contracts (including regulated futures contracts and non-equity options) entered into by the Fund will be governed by Section 1256 of the Code (“Section 1256 contracts”). Gains (or losses) on these contracts generally are considered to be 60% long-term and 40% short-term capital gains or losses (“60/40”), although foreign currency gains or losses arising from certain Section 1256 contracts may be treated as ordinary in character (see “Foreign Currency Transactions” below). Also, section 1256 contracts held by a Fund at the end of each taxable year (and for purposes of the 4% excise tax, on certain other dates prescribed in the Code) are “marked-to-market” with the result that unrealized gains or losses are treated as though they were realized and the resulting gains or losses are treated as ordinary or 60/40 gains or losses, as appropriate.
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
If you are “going long” on Bitcoin, you assume that Bitcoin prices will go up. And if you expect Bitcoin prices to go up, you are interested in buying call options – options that enable you to buy Bitcoin at a predetermined price in the future. For example, if the current Bitcoin price is 5,000 USD and you expect it to rise to 8,000 USD 6 months from now, you would certainly pay good money for a call option that allows you to purchase Bitcoin for 5000 USD in 6 months, when everyone else is buying for 8,000 USD.
