<>As a cryptocurrency attracts more interest, mining becomes harder and the amount of coins received as a reward decreases. For example, when Bitcoin was first created, the reward for successful mining was 50 BTC. Now, the reward stands at 12.5 Bitcoins. This happened because the Bitcoin network is designed so that there can only be a total of 21 mln coins in circulation. >
<>On 21 November 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USDT from their primary wallet. The company has 'tagged' the stolen currency, hoping to 'lock' them in the hacker's wallet (making them unspendable). Tether indicates that it is building a new core for its primary wallet in response to the attack in order to prevent the stolen coins from being used. >
<>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. >
<>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. >
<>Cryptocurrencies hold the promise of making it easier to transfer funds directly between two parties in a transaction, without the need for a trusted third party such as a bank or credit card company; these transfers are facilitated through the use of public keys and private keys for security purposes. In modern cryptocurrency systems, a user's "wallet," or account address, has the public key, and the private key is used to sign transactions. Fund transfers are done with minimal processing fees, allowing users to avoid the steep fees charged by most banks and financial institutions for wire transfers. >
<>The monetary policies of the Federal Reserve Bank during the 2010s led to the short-term interest rates—the rates banks pay to borrow money from one another—hovering around zero percent. The near zero rates meant money market fund investors saw returns significantly lower, compared to those in the prior decades. Further, with the tightening of regulations after the 2008 financial crisis, the number of investable securities grew smaller. >
The profit you made on the above theoretical trade depends on how much of the currency you purchased. If you bought 1,000 units (called a micro lot) each pip is worth $0.10, so you would calculate your profit as (50 pips * $0.10) = $5 for a 50 pip gain. If you bought a 10,000 unit (mini lot), then each pip is worth $1, so your profit ends up being $50. If you bought a 100,000 unit (standard lot) each pip is worth $10, so your profit is $500. This assumes you have a USD trading account.
Many people believe that cryptocurrencies are the hottest investment opportunity currently available. Indeed, there are many stories of people becoming millionaires through their Bitcoin investments. Bitcoin is the most recognizable digital currency to date, and just last year one BTC was valued at $800. In November 2017, the price of one Bitcoin exceeded $7,000.
An investor can profit from the difference between two interest rates in two different economies by buying the currency with the higher interest rate and shorting the currency with the lower interest rate. Prior to the 2008 financial crisis, it was very common to short the Japanese yen (JPY) and buy British pounds (GBP) because the interest rate differential was very large. This strategy is sometimes referred to as a "carry trade."
<>More specifically, the spot market is where currencies are bought and sold according to the current price. That price, determined by supply and demand, is a reflection of many things, including current interest rates, economic performance, sentiment towards ongoing political situations (both locally and internationally), as well as the perception of the future performance of one currency against another. When a deal is finalized, this is known as a "spot deal". It is a bilateral transaction by which one party delivers an agreed-upon currency amount to the counter party and receives a specified amount of another currency at the agreed-upon exchange rate value. After a position is closed, the settlement is in cash. Although the spot market is commonly known as one that deals with transactions in the present (rather than the future), these trades actually take two days for settlement. >
<>In the wake of the crisis two solutions have been proposed. One, repeatedly supported over the long term by the GAO and others is to consolidate the U.S. financial industry regulators. A step along this line has been the creation of the Financial Stability Oversight Council to address systemic risk issues that have in the past, as amply illustrated by the money market fund crisis above, fallen neatly between the cracks of the standing isolated financial regulators. Proposals to merge the SEC and CFTC have also been made. >
Hedge funds – Somewhere around 70 to 90% of all foreign exchange transactions are speculative in nature. This means, the person or institutions that bought or sold the currency has no plan of actually taking delivery of the currency; instead, the transaction was executed with sole intention of speculating on the price movement of that particular currency. Retail speculators (you and I) are small cheese compared to the big hedge funds that control and speculate with billions of dollars of equity each day in the currency markets.
<>Money market funds seek a stable net asset value, or NAV per share (which is generally $1.00 in the United States); they aim to never lose money. The $1.00 is maintained through the declaration of dividends to shareholders, typically daily, at an amount equal to the fund's net income. If a fund's NAV drops below $1.00, it is said that the fund "broke the buck". For SEC registered money funds, maintaining the $1.00 flat NAV is usually accomplished under a provision under Rule 2a-7 of the 40 Act that allows a fund to value its investments at amortized cost rather than market value, provided that certain conditions are maintained. One such condition involves a side-test calculation of the NAV that uses the market value of the fund's investments. The fund's published, amortized value may not exceed this market value by more than 1/2 cent per share, a comparison that is generally made weekly. If the variance does exceed $0.005 per share, the fund could be considered to have broken the buck, and regulators may force it into liquidation. >
Governments / Central banks – A country’s central bank can play an important role in the foreign exchange markets. They can cause an increase or decrease in the value of their nation’s currency by trying to control money supply, inflation, and (or) interest rates. They can use their substantial foreign exchange reserves to try and stabilize the market.
<>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. Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement. This difficulty is derived from leveraging cryptographic technologies.
