Monero is the most prominent example of the CryptoNight algorithm. This algorithm was invented to add the privacy features Bitcoin is missing. If you use Bitcoin, every transaction is documented in the blockchain and the trail of transactions can be followed. With the introduction of a concept called ring-signatures, the CryptoNight algorithm was able to cut through that trail.
<>An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017. Popular favorites of cryptocurrency miners such as Nvidia's GTX 1060 and GTX 1070 graphics cards, as well as AMD's RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock. A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available. >
<>Under the provisions, a money fund mainly invests in the top-rated debt instruments, and they should have a maturity period under 13 months. The money market fund portfolio is required to maintain a weighted average maturity (WAM) period of 60 days or less. This WAM requirement means that the average maturity period of all the invested instruments taken in proportion to their weights in the fund portfolio should not be more than 60 days. This maturity limitation is done to ensure that only highly liquid instruments qualify for investments, and the investor’s money is not locked-in long maturity instruments that can mar the liquidity. >
To realize digital cash you need a payment network with accounts, balances, and transaction. That‘s easy to understand. One major problem every payment network has to solve is to prevent the so-called double spending: to prevent that one entity spends the same amount twice. Usually, this is done by a central server who keeps record about the balances.

<>Decentralized cryptocurrency is produced by the entire cryptocurrency system collectively, at a rate which is defined when the system is created and which is publicly known. In centralized banking and economic systems such as the Federal Reserve System, corporate boards or governments control the supply of currency by printing units of fiat money or demanding additions to digital banking ledgers. In case of decentralized cryptocurrency, companies or governments cannot produce new units, and have not so far provided backing for other firms, banks or corporate entities which hold asset value measured in it. The underlying technical system upon which decentralized cryptocurrencies are based was created by the group or individual known as Satoshi Nakamoto. >
<>As the SEC was gridlocked, the Financial Stability Oversight Council promulgated its own suggested money market reforms and threatens to move forward if the SEC doesn’t button it up with an acceptable solution of their own on a timely basis. The SEC has argued vociferously that this is "their area" and FSOC should back off and let them handle it, a viewpoint shared by four former SEC Chairmen Roderick Hills, David Ruder, Richard Breeden, and Harvey Pitt, and two former commissioners Roel Campos and Paul S. Atkins. >
The semi-anonymous nature of cryptocurrency transactions makes them well-suited for a host of nefarious activities, such as money laundering and tax evasion. However, cryptocurrency advocates often value the anonymity highly. Some cryptocurrencies are more private than others. Bitcoin, for instance, is a relatively poor choice for conducting illegal business online, and forensic analysis of bitcoin transactions has led authorities to arrest and prosecute criminals. More privacy-oriented coins do exist, such as Dash, ZCash, or Monero, which are far more difficult to trace.
<>The “requesting a transaction” means you want to transfers some coins (let’s say bitcoin) to someone else. When you make the request the request is broadcasted to all the nodes. Then the nodes verify that (from all the history of transactions) you are not double spending your coins. When verified successfully the transaction is added in a block which is then mined by a miner. When the block is mined, your transaction is confirmed and the coins are transfered. >
Money market funds seek to limit exposure to losses due to credit, market, and liquidity risks. Money market funds in the United States are regulated by the Securities and Exchange Commission (SEC) under the Investment Company Act of 1940. Rule 2a-7 of the act restricts the quality, maturity and diversity of investments by money market funds. Under this act, a money fund mainly buys the highest rated debt, which matures in under 13 months. The portfolio must maintain a weighted average maturity (WAM) of 60 days or less and not invest more than 5% in any one issuer, except for government securities and repurchase agreements.
<>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. >
There are also funds which are billed as "money market funds", but are not 2a-7 funds (do not meet the requirements of the rule). In addition to 2a-7 eligible securities, these funds invest in Eurodollars and repos (repurchase agreements), which are similarly liquid and stable to 2a-7 eligible securities, but are not allowed under the regulations.
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.
<>In 2008, following the bankruptcy of Lehman Brothers, the venerable Reserve Primary Fund broke the buck: It held millions of Lehman's debt obligations, and panicked redemptions by its investors caused its NAV to fall to 97 cents per share. The pullout of money caused the Reserve Primary Fund to close and triggered mayhem throughout the money markets.
