<>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. >
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.
<>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. >
<>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.

<>This is a bank run in the sense that there is a mismatch in maturities, and thus a money fund is a "virtual bank": the assets of money funds, while short term, nonetheless typically have maturities of several months, while investors can request redemption at any time, without waiting for obligations to come due. Thus if there is a sudden demand for redemptions, the assets may be liquidated in a fire sale, depressing their sale price.

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.

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.
Forex, also known as foreign exchange, FX or currency trading, is a decentralized global market where all the world's currencies trade. The forex market is the largest, most liquid market in the world with an average daily trading volume exceeding $5 trillion. All the world's combined stock markets don't even come close to this. But what does that mean to you? Take a closer look at forex trading and you may find some exciting trading opportunities unavailable with other investments.
Transactions that occur through the use and exchange of these altcoins are independent from formal banking systems, and therefore can make tax evasion simpler for individuals. Since charting taxable income is based upon what a recipient reports to the revenue service, it becomes extremely difficult to account for transactions made using existing cryptocurrencies, a mode of exchange that is complex and difficult to track.
While cryptocurrencies are digital currencies that are managed through advanced encryption techniques, many governments have taken a cautious approach toward them, fearing their lack of central control and the effects they could have on financial security. Regulators in several countries have warned against cryptocurrency and some have taken concrete regulatory measures to dissuade users. Additionally, many banks do not offer services for cryptocurrencies and can refuse to offer services to virtual-currency companies. Gareth Murphy, a senior central banking officer has stated "widespread use [of cryptocurrency] would also make it more difficult for statistical agencies to gather data on economic activity, which are used by governments to steer the economy". He cautioned that virtual currencies pose a new challenge to central banks' control over the important functions of monetary and exchange rate policy. While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if bitcoins are lost or stolen. One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.

The validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.

<>Short Term Variable NAV – Short-term Variable Net Asset Value (VNAV) MMFs are primarily invested in money market instruments, deposits and other MMFs.

<>Continuing investor anxiety as a result of the Lehman Brothers bankruptcy and other pending financial troubles caused significant redemptions from money funds in general, as investors redeemed their holdings and funds were forced to liquidate assets or impose limits on redemptions. Through Wednesday, September 17, 2008, prime institutional funds saw substantial redemptions. Retail funds saw net inflows of $4 billion, for a net capital outflow from all funds of $169 billion to $3.4 trillion (5%). >

In the 1970s, money market funds began disintermediating banks from their classic interposition between savers and borrowers. The funds provided a more direct link, with less overhead. Large banks are regulated by the Federal Reserve Board and the Office of the Comptroller of the Currency. Notably, the Fed is itself owned by the large private banks, and controls the overall supply of money in the United States. The OCC is housed within the Treasury Department, which in turn manages the issuance and maintenance of the multi-trillion dollar debt of the U.S. government. The overall debt is of course connected to ongoing federal government spending vs. actual ongoing tax receipts. Unquestionably, the private banking industry, bank regulation, the national debt, and ongoing governmental spending politics are substantially interconnected. Interest rates incurred on the national debt is subject to rate setting by the Fed, and inflation (all else being equal) allows today's fixed debt obligation to be paid off in ever cheaper to obtain dollars. The third major bank regulator, designed to swiftly remove failing banks is the Federal Deposit Insurance Corporation, a bailout fund and resolution authority that can eliminate banks that are failing, with minimum disruption to the banking industry itself. They also help ensure depositors continue to do business with banks after such failures by insuring their deposits.

Bitcoin is pseudonymous rather than anonymous in that the cryptocurrency within a wallet is not tied to people, but rather to one or more specific keys (or "addresses"). Thereby, bitcoin owners are not identifiable, but all transactions are publicly available in the blockchain. Still, cryptocurrency exchanges are often required by law to collect the personal information of their users.
<>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.
