Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[30] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[1] This difficulty is derived from leveraging cryptographic technologies.

Cryptocurrency is also used in controversial settings in the form of online black markets, such as Silk Road. The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[84]
On May 7, 2014, the SEC published an investor alert that highlighted fraud and other concerns relating to certain investment opportunities denominated in bitcoin and fraudulent and unregistered investment schemes targeted at participants in online bitcoin forums. On July 25, 2017, the SEC issued a Report of Investigation or Report which concluded that digital assets or tokens issued for the purpose of raising funds may be securities within the meaning of the federal securities laws. The Report emphasized that whether a digital asset is a security is based on the particular facts and circumstances, including the economic realities of the transactions. This was reiterated in a December 11, 2017 Public Statement emphasizing the risks of investing in digital assets such as bitcoin and noting the possibility that bitcoin and other digital assets may be deemed to be securities. The SEC continues to take action against persons or entities misusing bitcoin in connection with fraudulent schemes (i.e., Ponzi scheme), inaccurate and inadequate publicly disseminated information, and the offering of unregistered securities.

•   New Fund Risk — The Fund recently commenced operations, has a limited operating history, and started operations with a small asset base. There can be no assurance that the Fund will be successful or grow to or maintain a viable size, that an active trading market for the Fund’s shares will develop or be maintained, or that the Fund’s shares’ listing will continue unchanged.

While volatile movements take away the attractiveness of any asset, a certain amount of swing in price creates trading opportunities. This is something that many traders and speculators have been taking advantage of by buying the digital currency and then selling at a profit through an exchange. The whole process makes bitcoin exchanges an important part of the ecosystem since it facilitates the buying and selling of bitcoins, as well as futures trading.
Investments in common units of MLPs involve risks that differ from investments in common stock. Holders of common units of MLPs have the rights typically provided to limited partners in limited partnerships and, thus, may have limited control and limited voting rights as compared to holders of a corporation’s common shares. Holders of common units may be subject to conflicts of interest with the MLP’s general partner, including those arising from incentive distribution payments. MLPs may also have limited financial resources and units may be subject to cash flow and dilution risk. In addition, investments held by MLPs may be relatively illiquid, limiting the MLPs’ ability to vary their portfolios promptly in response to changes in economic or other conditions. Accordingly, MLPs may be subject to more erratic price movements because of the underlying assets they hold. Further, a Fund’s investment in MLPs subjects the Fund to the risks associated with the specific industry or industries in which the MLPs invest.
The Funds may invest in bitcoin-based futures contracts, swap agreements, and options contracts, which are types of derivative contracts. A derivative refers to any financial instrument whose value is derived, at least in part, from the price of an underlying security, commodity, asset, rate, or index. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. Changes in the value of a derivative may not correlate perfectly with the underlying security, asset, rate or index. Gains or losses in a derivative may be magnified and may be much greater than the derivative’s original cost. Because bitcoin-based derivatives were only recently introduced, the degree to which bitcoin-based derivatives are likely to provide exposure to movements in the price of bitcoin is extremely uncertain. If market participants executing trades in bitcoin-based derivatives face constraints, including capital constraints, security risks, or high execution costs with respect to direct investments in bitcoin, the price at which bitcoin-based derivatives trade may fail to capture price movements in the underlying price of bitcoin. Moreover, it is not clear how changes to the Bitcoin Network and determinations by any relevant derivatives exchange with respect to such changes to the Bitcoin Network will affect the value of any positions in bitcoin-based derivatives. [[In December 2015, the SEC proposed a new rule to regulate the use of derivatives by registered investment companies, such as the Fund. Whether and when this proposed rule will be adopted and its potential effects on the Fund are unclear as of the date of this Prospectus.]]
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.
After the Transfer Agent has deemed an order for redemption outside the Clearing Process received, the Transfer Agent will initiate procedures to transfer the requisite Fund Securities and the Balancing Amount (minus a redemption Transaction Fee or additional charges for requested cash redemptions), which are expected to be delivered within two Business Days, and the Cash Redemption Amount (by the second Business Day (T+2) following the transmittal date on which such redemption order is deemed received by the Transfer Agent).
While “physical” delivery of Bitcoins as part of a futures contract would certainly be possible it raises regulatory and security issues in today’s environment where the cybercurrency exchanges are mostly unregulated, somewhat unreliable, and theft due to security hacks is distressingly common.  By selecting cash settlement the CME and Cboe completely avoid the transfer of custody issues and shift those problems to somebody else—namely the market makers and arbitrageur.
According to PricewaterhouseCoopers, four of the 10 biggest proposed initial coin offerings have used Switzerland as a base, where they are frequently registered as non-profit foundations. The Swiss regulatory agency FINMA stated that it would take a “balanced approach“ to ICO projects and would allow “legitimate innovators to navigate the regulatory landscape and so launch their projects in a way consistent with national laws protecting investors and the integrity of the financial system.” In response to numerous requests by industry representatives, a legislative ICO working group began to issue legal guidelines in 2018, which are intended to remove uncertainty from cryptocurrency offerings and to establish sustainable business practices.[65]
Daily Position Limit Risk - Many U.S. futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. Once the daily limit has been reached in a particular contract, no trades may be made that day at a price beyond that limit or trading may be suspended for specified periods during the trading day. In addition, these exchanges have established limits on the maximum amount of futures positions that any person may hold or control on such exchanges. These limits may restrict the amount of assets the Fund is able to invest in bitcoin futures contracts or have a
These developments are expected to not only further rally the price of Bitcoin, but also open the doors for more traditional investment opportunities based on cryptocurrencies, such as a Bitcoin exchange-traded fund (ETF). ETFs are currently very popular investment products for beginning and advanced investors because they charge low fees and usually have low volatility. Because high volatility is one of the factors preventing conventional investors from entering the crypto market, products such as these could offer them the best of both worlds.
The Advisor, with the assistance of ISS, maintains for a period of at least five years a record of each proxy statement received and materials that were considered when the proxy was voted during the calendar year. Information on how the Funds voted proxies relating to portfolio securities for the 12-month (or shorter) period ended June 30 is available without charge, upon request, (1) by calling the Advisor at 888-776-3637, (2) on the Trust’s website at, and (3) on the SEC’s website at
Each Fund may enter into reverse repurchase agreements as part of its investment strategy, which may be viewed as a form of borrowing. Reverse repurchase agreements involve sales by a Fund of portfolio assets for cash concurrently with an agreement by the Fund to repurchase those same assets at a later date at a fixed price. Generally, the effect of such a transaction is that a Fund can recover all or most of the cash invested in the portfolio securities involved during the term of the reverse repurchase agreement, while a Fund will be able to keep the interest income associated with those portfolio securities. Such transactions are advantageous only if the interest cost to a Fund of the reverse repurchase transaction is less than the cost of obtaining the cash otherwise. Opportunities to achieve this advantage may not always be available, and a Fund intends to use the reverse repurchase technique only when it will be to the Fund’s advantage to do so. A Fund will segregate with its custodian bank cash or liquid instruments equal in value to the Fund’s obligations with respect to reverse repurchase agreements.
For purchases and sales of derivatives (i.e., financial instruments whose value is derived from the value of an underlying asset, interest rate or index) the Advisor evaluates counterparties on the following factors: reputation and financial strength; execution prices; commission costs; ability to handle complex orders; ability to give prompt and full execution, including the ability to handle difficult trades; accuracy of reports and confirmations provided; reliability, type and quality of research provided; financing costs and other associated costs related to the transaction; and whether the total cost or proceeds in each transaction is the most favorable under the circumstances.
The Officers, under the supervision of the Board, manage the day-to-day operations of the Trust. One Trustee and all of the Officers of the Trust are directors, officers or employees of ProShare Advisors or Foreside Management Services, LLC. The other Trustees are Independent Trustees. The Trustees and some Officers are also directors and officers of some or all of the other funds in the Fund Complex. The Fund Complex includes all funds advised by ProShare Advisors and any funds that have an investment adviser that is an affiliated person of ProShare Advisors.
  8. Except for the Managed Futures Strategy ETF, the Crude Oil Strategy ETF and the CDS Short North American HY Credit ETF, concentrate (i.e., hold more than 25% of its assets in the stocks of a single industry or group of industries) its investments in issuers of one or more particular industries, except that a Fund will concentrate to approximately the same extent that its index concentrates in the stocks of such particular industry or industries. For purposes of this limitation, securities of the U.S. government (including its agencies and instrumentalities) and tax-free securities of state or municipal governments and their political subdivisions (and repurchase agreements collateralized by government securities) are not considered to be issued by members of any industry. For purposes of determining whether the Funds are concentrated in an industry or group of industries, each Fund may concentrate its investment in the securities of companies engaged in a single industry or group of industries to approximately the same extent as its benchmark and in accordance with its investment objective and policies as disclosed in the Prospectus and SAI.
A distribution will be treated as paid on December 31 of a calendar year if it is declared by a Fund in October, November or December of that year with a record date in such a month and is paid by the Fund during January of the following year. Such distributions will be taxable to shareholders in the calendar year in which the distributions are declared, rather than the calendar year in which the distributions are received.
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.

A Precautionary Note to Purchasers of Creation Units — You should be aware of certain legal risks unique to investors purchasing Creation Units directly from the fund. Because new shares from the Fund may be issued on an ongoing basis, a “distribution” of the Fund’s shares could be occurring at any time. As a dealer, certain activities on your part could, depending on the circumstances, result in your being deemed a participant in the distribution, in a manner that could render you a statutory underwriter and subject you to the prospectus delivery and liability provisions of the Securities Act of 1933, as amended (the “Securities Act”). For example, you could be deemed a statutory underwriter if you purchase Creation Units from the Fund, break them down into the constituent Fund shares, and sell those shares directly to customers, or if you choose to couple the creation of a supply of new shares with an active selling effort involving solicitation of secondary market demand for shares. Whether a person is an underwriter depends upon all of the facts and circumstances pertaining to that person’s activities, and the examples mentioned here should not be considered a complete description of all the activities that could cause you to be deemed an underwriter. Dealers who are not “underwriters,” but are
Traders do NOT need to wait until settlement in order to get out of position and profit from the trade. Bob or Ann can pass off their side of the future contract to someone else. So Bob, who is long, can sell the contract at a different price to Sally, who wants to hold the long side of the contract where Ann is short. So if Sally puts a bid order in the January 9 futures orderbook at $410, then Bob can sell his contract to Sally, earning a nice 2.5% return nominally, or 12.5% (5x) return on the 0.2 BTC initial margin used. In this sense, the contracts are just like trading spot!
This may sound like an unfair system to those who are used to trading with confidence that their profits are settled in full, but it's a compromise that has been made in order to offer the high leverage. If you want to guarantee that your profits are not reduced by any socialised loss, then use CryptoFacilities or Coinpit. They use a "termination" procedure in the event of a margin call not being filled. This simply terminates the contract and sends the portfolio value of the losing counterparty to the winning counterparty. It's worth noting that the system has been incredibly robust, with very minimal socialised losses being triggered on OKCoin and none on BitMEX as of November 2015.

BitMEX is a derivatives exchange that offers leveraged contracts that are bought and sold in Bitcoin. This is a platform that provides trading in bitcoin derivatives. The derivative traded is a perpetual swap contract, which is a derivative product similar to a traditional Futures Contract. Swap contracts trade like spots, tracking the underlying assets.

The method by which Creation Units are created and traded may raise certain issues under applicable securities laws. Because new Creation Units are issued and sold by the Trust on an ongoing basis, at any point a “distribution,” as such term is used in the 1933 Act, may occur. Broker-dealers and other persons are cautioned that some activities on their part may, depending on the circumstances, result in their being deemed participants in a distribution in a manner which could render them statutory underwriters and subject them to the prospectus delivery and liability provisions of the 1933 Act. For example, a broker-dealer firm or its client may be deemed a statutory underwriter if it takes Creation Units after placing an order with the Distributor, breaks them down into constituent Shares and sells some or all of the Shares comprising such Creation Units directly to its customers; or if it chooses to couple the creation of a supply of new Shares with an active selling effort involving solicitation of secondary market demand for Shares. A determination of whether a person is an underwriter for the purposes of the 1933 Act depends upon all the facts and circumstances pertaining to that person’s activities. Thus, the examples mentioned above should not be considered a complete description of all the activities that could lead a person to be deemed an underwriter. Broker-dealer firms should also note that dealers who are effecting transactions in Shares, whether or not participating in the distribution of Shares, are generally required to deliver a prospectus. This is because the prospectus delivery exemption in Section 4(3) of the 1933 Act is not available in respect of such transactions as a result

The CME considers a hard fork of the Bitcoin Blockchain where both forks continue to be actively mined and traded but may not be fungible with each other, as an unusual and extreme circumstance. As such, CME provides that Crypto Facilities Ltd. (CME’s administrator) shall be responsible for recommending the necessary actions and responses to ensure the relevance and integrity of the Bitcoin Pricing Products.
There may be circumstances outside the control of the Advisor, Trust, Administrator (as defined below), transfer agent, Custodian (as defined below), any sub-custodian, Distributor (as defined below), and/or a Fund that make it, for all practical purposes, impossible to re-position such Fund and/or to process a purchase or redemption order. Examples of such circumstances include: natural disasters; public service disruptions or utility problems such as those caused by fires, floods, extreme weather conditions, and power outages resulting in telephone, telecopy, and computer failures; market conditions or activities causing trading halts; systems failures involving computer or other information systems affecting the aforementioned parties, as well as the DTC, the NSCC, or any other participant in the purchase process; and similar extraordinary events. Accordingly, while the Advisor has implemented and tested a business continuity plan that transfers functions of any disrupted facility to another location and has effected a disaster recovery plan, circumstances, such as those above, may prevent a Fund from being operated in a manner consistent with its investment objective and/or principal investment strategies.
With the increased use of technologies such as the Internet and the dependence on computer systems to perform necessary business functions, the Funds and the digital assets that underline the bitcoin futures contracts in which the Funds invest are susceptible to operational and information security risk. The digital nature of bitcoins and the irreversible nature of bitcoin transactions makes bitcoin an attractive target for theft, hacking and other cyber-attacks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber-attacks include, but are not limited to gaining unauthorized access to digital systems for purposes of misappropriating assets such as bitcoin or other cryptocurrencies or gaining access to sensitive information, corrupting data, or causing operational disruption. Cyber-attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites. Such events have historically correlated with a drop in the price of bitcoin, which may adversely affect your investment in a Fund. Cyber security failures or breaches of a Fund’s third party service provider (including, but not limited to, index providers, the administrator and transfer agent) or the issuers of the bitcoin futures contracts in which the Funds invest, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of a Fund’s shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. The Funds their service providers, counterparties and other market participants on which the Funds rely could be negatively impacted as a result. While the Funds have established business continuity plans and systems to prevent such cyber-attacks, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified.
Creation Units of Shares may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor. Such Authorized Participant will agree pursuant to the terms of such Authorized Participant Agreement on behalf of itself or any investor on whose behalf it will act, as the case may be, to certain conditions, including that such Authorized Participant will make available an amount of cash sufficient to pay the Balancing Amount, defined below, and the Transaction Fee, described below in “Transaction Fees”. The Authorized Participant may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Balancing Amount. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement, and that therefore orders to purchase Creation Units may have to be placed by the investor’s broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants.

the option to purchase the asset underlying the option at the exercise price if the option is exercised. During the term of the option, the writer may be assigned an exercise notice by the broker-dealer through whom the option was sold. The exercise notice would require the writer to deliver, in the case of a call, or take delivery of, in the case of a put, the underlying asset against payment of the exercise price. This obligation terminates upon expiration of the option, or at such earlier time that the writer effects a closing purchase transaction by purchasing an option covering the same underlying asset and having the same exercise price and expiration date as the one previously sold. Once an option has been exercised, the writer may not execute a closing purchase transaction. To secure the obligation to deliver the underlying asset in the case of a call option, the writer of a call option is required to deposit in escrow the underlying asset or other assets in accordance with the rules of the Options Clearing Corporation (the “OCC”), an institution created to interpose itself between buyers and sellers of options. The OCC assumes the other side of every purchase and sale transaction on an exchange and, by doing so, gives its guarantee to the transaction. When writing call options on an asset, a Fund may cover its position by owning the underlying asset on which the option is written. Alternatively, the Fund may cover its position by owning a call option on the underlying asset, on a share-for-share basis, which is deliverable under the option contract at a price no higher than the exercise price of the call option written by the Fund or, if higher, by owning such call option and depositing and segregating cash or liquid instruments equal in value to the difference between the two exercise prices. In addition, a Fund may cover its position by segregating cash or liquid instruments equal in value to the exercise price of the call option written by the Fund. When a Fund writes a put option, the Fund will segregate with its custodian bank cash or liquid instruments having a value equal to the exercise value of the option. The principal reason for a Fund to write call options on assets held by the Fund is to attempt to realize, through the receipt of premiums, a greater return than would be realized on the underlying assets alone.
  •   A new competing digital asset may pose a challenge to bitcoin’s current market dominance, resulting in a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin. It is possible that other digital currencies and trading systems could become more widely accepted and used than Bitcoin. The rise of such currencies could lead to a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin.

Commodity Swaps. Commodity swaps are used either as substitutes for owning a specific physical commodities or as a means of obtaining non-leveraged exposure in markets where a specific commodity is not available. Commodity swaps provide the Fund with the additional flexibility of gaining exposure to commodities by using the most cost-effective vehicle available.
In connection with its management of certain series of the Trust (i.e., the UltraShort S&P500®, the UltraShort QQQ®, the UltraShort Dow 30SM, the UltraShort MidCap400, the UltraShort SmallCap600, the UltraPro Short S&P500®, the UltraPro Short QQQ®, the UltraShort Basic Materials, the UltraShort Financials, the UltraShort Utilities, the UltraPro Short Nasdaq Biotechnology, the UltraPro MidCap 400, the UltraPro S&P 500®, the UltraPro QQQ®, the UltraPro Dow 30SM, the UltraPro Russell 2000, the UltraPro Nasdaq Biotechnology and the UltraPro Financial Select Sector) and the wholly owned subsidiary of each of the Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF (i.e., ProShares Cayman Portfolio I, ProShares Cayman Crude Oil Portfolio, ProShares Cayman Bitcoin Futures Strategy Portfolio ProShares Cayman Short Bitcoin Futures Strategy Portfolio, ProShares Cayman Bitcoin Futures/Equity Strategy Portfolio and ProShares Cayman Bitcoin/Blockchain Strategy Portfolio, respectively) (collectively, the “Commodity Pools”) the Advisor has registered as a commodity pool operator (a “CPO”) and the Commodity Pools are commodity pools under the Commodity Exchange Act (the “CEA”). Accordingly, the Advisor is subject to registration and regulation as a CPO under the CEA, and must comply with various regulatory requirements under the CEA and the rules and regulations of the CFTC and the National Futures Association (“NFA”), including investor protection requirements, antifraud provisions, disclosure requirements and reporting and recordkeeping requirements. The Advisor is also subject to periodic inspections and audits by the CFTC and NFA. Compliance with these regulatory requirements could adversely affect the Commodity Pools’ total return. In this regard, any further amendment to the CEA or its related regulations that subject the Advisor or the Commodity Pools to additional regulation may have adverse impacts on the Commodity Pools’ operations and expenses.
  •   The bitcoin exchanges on which bitcoin trades are relatively new and, in most cases, largely unregulated and, therefore, may be more exposed to volatility, fraud and security breaches than established, regulated exchanges for other products. Over the past several years, a number of Bitcoin Exchanges have been closed due to fraud, failure, security breaches or governmental regulations. The nature of the assets held at Bitcoin Exchanges make them appealing targets for hackers and a number of Bitcoin Exchanges have been victims of cybercrimes. No Bitcoin Exchange is immune from these risks. Fraudulent activity can increase volatility and have an adverse effect on the price of bitcoin, the general acceptance of bitcoin as an investment or means of currency and could have a negative impact on the bitcoin futures contracts in which the Fund invests and the value of the Fund.
(c) distribute with respect to each taxable year at least 90% of the sum of its investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid—generally, taxable ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and net tax-exempt interest income, for such year.
A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.[1][2][3] Cryptocurrencies are a kind of alternative currency and digital currency (of which virtual currency is a subset). Cryptocurrencies use decentralized control[4] as opposed to centralized digital currency and central banking systems.[5] The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.[6][7]

Sub or Substratum is another open-source network with a huge focus on decentralizing the web and on “making the internet a free and fair place for the entire world.” This platform allows content creators to freely host their websites or applications on Substratum host, without any censorship blocks. Network users can then “run” Sub nodes and help the content get forwarded to end web users, who can access all Sub content in regular web browsers without any blocks or limits in shape of censorship.
Most traders who do not have a plan for trading blindly will be eliminated in the near future. As a transaction, bitcoin trading is no different from other underlying objects, such as stock futures. An effective trading strategy is essential in order to make a steady profit in this market. Stop the loss of profits, homeopathy, light warehouse is the key. To strictly implement these trading plan, use the program trading is very effective, program trading my first contact with bitcoin is BotVS quantification in the know the platform to see the column introduced bitcoin hedging strategy is inspired by. Later, I tried to write some trading strategies and use them on firm exchanges. Accumulated a lot of bitcoin trading experience. I’m still bullish on bitcoin, which was a great invention in the twenty-first Century.
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.
UPDATE: I do not recommend paying to enter a Cryptocurrency mastermind group – I’ve tried a few and found the ROI to be disappointing. I am now focussing on growing my portfolio passively utilising a cryptocurrency trading bot, the renowned Notorious Bot. Having a bot that trades for me, without emotion, using an advanced algorithm, allows me to grow my portfolio in the background without it cutting into my time or stressing me out. You can familiarise yourself with the basics of cryptocurrency trading bots here. 
Important agents interacting with those prices are operating in one of three roles: individual speculator, market maker, or arbitrageur. A key role is market maker—a firm that has agreed to simultaneously act as both a buyer and seller for a specific security. When companies sign up for this role they agree to keep the bid/ask prices relatively close to each other—for example even if they aren’t keen on selling Bitcoins at the moment they can’t just set the ask price to an outrageous level. The agreed-upon maximum bid/ask ranges might be tied to market conditions (e.g., wider when deemed a “fast market”) and might allow time-outs but in general, the market maker agrees to act as a buffer between supply and demand.
