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.
<>Transaction fees for cryptocurrency depend mainly on the supply of network capacity at the time, versus the demand from the currency holder for a faster transaction. The currency holder can choose a specific transaction fee, while network entities process transactions in order of highest offered fee to lowest. Cryptocurrency exchanges can simplify the process for currency holders by offering priority alternatives and thereby determine which fee will likely cause the transaction to be processed in the requested time. >
In the 1990s, bank interest rates in Japan were near zero for an extended period of time. To search for higher yields from these low rates in bank deposits, investors used money market funds for short-term deposits instead. However, several money market funds fell off short of their stable value in 2001 due to the bankruptcy of Enron, in which several Japanese funds had invested, and investors fled into government-insured bank accounts. Since then the total value of money markets have remained low.
<> Assets are invested in any eligible U.S. dollar-denominated money market instruments as defined by applicable U.S. Securities and Exchange Commission regulations (Rule 2a-7 of the Investment Company Act of 1940), including all types listed above as well as commercial paper, certificates of deposit, corporate notes, and other private instruments from domestic and foreign issuers, as well as repurchase and potentially reverse repurchase agreements. >
One of the most important problems that any payment network has to solve is double-spending. It is a fraudulent technique of spending the same amount twice. The traditional solution was a trusted third party - a central server - that kept records of the balances and transactions. However, this method always entailed an authority basically in control of your funds and with all your personal details on hand.
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.
<>As major economies across the globe—including the U.S.—followed QE measures in the aftermaths of the 2008 financial crisis, a good portion of the QE money made its way into money market mutual funds as a haven. This migration of funds has led to interest rates remaining low for a long duration, and the diminishing of returns from money market funds. >
<>1) Controlled supply: Most cryptocurrencies limit the supply of the tokens. In Bitcoin, the supply decreases in time and will reach its final number sometime around the year 2140. All cryptocurrencies control the supply of the token by a schedule written in the code. This means the monetary supply of a cryptocurrency in every given moment in the future can roughly be calculated today. There is no surprise.

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.
<>The term altcoin has various similar definitions. Stephanie Yang of The Wall Street Journal defined altcoins as "alternative digital currencies," while Paul Vigna, also of The Wall Street Journal, described altcoins as alternative versions of bitcoin. Aaron Hankins of the MarketWatch refers to any cryptocurrencies other than bitcoin as altcoins. >
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.
Take the money on your bank account: What is it more than entries in a database that can only be changed under specific conditions? You can even take physical coins and notes: What are they else than limited entries in a public physical database that can only be changed if you match the condition than you physically own the coins and notes? Money is all about a verified entry in some kind of database of accounts, balances, and transactions.
The legal status of cryptocurrencies varies substantially from country to country and is still undefined or changing in many of them. While some countries have explicitly allowed their use and trade, others have banned or restricted it. According to the Library of Congress, an "absolute ban" on trading or using cryptocurrencies applies in eight countries: Algeria, Bolivia, Egypt, Iraq, Morocco, Nepal, Pakistan, and the United Arab Emirates. An "implicit ban" applies in another 15 countries, which include Bahrain, Bangladesh, China, Colombia, the Dominican Republic, Indonesia, Iran, Kuwait, Lesotho, Lithuania, Macau, Oman, Qatar, Saudi Arabia and Taiwan. In the United States and Canada, state and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating "bitcoin scams" and ICOs in 40 jurisdictions.
<>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. >
