Properties of cryptocurrencies gave them popularity in applications such as a safe haven in banking crises and means of payment, which also led to the cryptocurrency use 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.
<>NEM — Unlike most other cryptocurrencies that utilize a Proof of Work algorithm, it uses Proof of Importance, which requires users to already possess certain amounts of coins in order to be able to get new ones. It encourages users to spend their funds and tracks the transactions to determine how important a particular user is to the overall NEM network. >
^ See Markus K. Brunnermeir,Deciphering the 2007-08 Liquidity and Credit Crunch, Journal of Economic Perspectives (May, 2008)(arguing that investment banks reliance on commercial paper and repo markets had increased over the last 3 years. This reliance is seen in the fact that 25% of assets purchased by investment banks had been funded through the repo market.)
A money market mutual fund is a type of fixed income mutual fund that invests in debt securities characterized by their short maturities and minimal credit risk. Money market mutual funds are among the lowest-volatility types of investments. Income generated by a money market fund can be either taxable or tax-exempt, depending on the types of securities in which the fund invests.
<>A Government money fund (as of the SEC's July 24, 2014 rule release) is one that invests at least 99.5% of its total assets in cash, government securities, and/or repurchase agreements that are “collateralized fully” (i.e., collateralized by cash or government securities). A Treasury fund is a type of government money fund that invests in US Treasury Bills, Bonds and Notes. >
<>In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt. This arms race for cheaper-yet-efficient machines has been on since the day the first cryptocurrency, bitcoin, was introduced in 2009. With more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs. Thus the value of the currency obtained for finding a hash often does not justify the amount of money spent on setting up the machines, the cooling facilities to overcome the enormous amount of heat they produce, and the electricity required to run them. >
<>Miners are the single most important part of any cryptocurrency network, and much like trading, mining is an investment. Essentially, miners are providing a bookkeeping service for their respective communities. They contribute their computing power to solving complicated cryptographic puzzles, which is necessary to confirm a transaction and record it in a distributed public ledger called the Blockchain. >
<>There are also purely technical elements to consider. For example, technological advancement in cryptocurrencies such as bitcoin result in high up-front costs to miners in the form of specialized hardware and software. Cryptocurrency transactions are normally irreversible after a number of blocks confirm the transaction. Additionally, cryptocurrency private keys can be permanently lost from local storage due to malware, data loss or the destruction of the physical media. This prevents the cryptocurrency from being spent, resulting in its effective removal from the markets. >
Retail Forex traders – Finally, we come to retail Forex traders (you and I). The retail Forex trading industry is growing everyday with the advent of Forex trading platforms and their ease of accessibility on the internet. Retail Forex traders access the market indirectly either through a broker or a bank. There are two main types of retail Forex brokers that provide us with the ability to speculate on the currency market: brokers and dealers. Brokers work as an agent for the trader by trying to find the best price in the market and executing on behalf of the customer. For this, they charge a commission on top of the price obtained in the market. Dealers are also called market makers because they ‘make the market’ for the trader and act as the counter-party to their transactions, they quote a price they are willing to deal at and are compensated through the spread, which is the difference between the buy and sell price (more on this later).
Banks in the United States offer savings and money market deposit accounts, but these should not be confused with money mutual funds. These bank accounts offer higher yields than traditional passbook savings accounts, but often with higher minimum balance requirements and limited transactions. A money market account may refer to a money market mutual fund, a bank money market deposit account (MMDA) or a brokerage sweep free credit balance.
An initial coin offering (ICO) is a controversial means of raising funds for a new cryptocurrency venture. An ICO may be used by startups with the intention of avoiding regulation. However, securities regulators in many jurisdictions, including in the U.S., and Canada have indicated that if a coin or token is an "investment contract" (e.g., under the Howey test, i.e., an investment of money with a reasonable expectation of profit based significantly on the entrepreneurial or managerial efforts of others), it is a security and is subject to securities regulation. In an ICO campaign, a percentage of the cryptocurrency (usually in the form of "tokens") is sold to early backers of the project in exchange for legal tender or other cryptocurrencies, often bitcoin or ether.
<>But while cryptocurrencies are more used for payment, its use as a means of speculation and a store of value dwarfs the payment aspects. Cryptocurrencies gave birth to an incredibly dynamic, fast-growing market for investors and speculators. Exchanges like Okcoin, Poloniex or shapeshift enables the trade of hundreds of cryptocurrencies. Their daily trade volume exceeds that of major European stock exchanges.
