You don‘t need to understand the details about SHA 256. It‘s only important you know that it can be the basis of a cryptologic puzzle the miners compete to solve. After finding a solution, a miner can build a block and add it to the blockchain. As an incentive, he has the right to add a so-called coinbase transaction that gives him a specific number of Bitcoins. This is the only way to create valid Bitcoins.
<>The SEC is giving money fund boards of directors the discretion whether to impose a liquidity fee if a fund’s weekly liquidity level falls below the required regulatory threshold, and/or to suspend redemptions temporarily, i.e., to "gate" funds, under the same circumstances. These amendments will require all non-government money funds to impose a liquidity fee if the fund’s weekly liquidity level falls below a designated threshold, unless the fund’s board determines that imposing such a fee is not in the best interests of the fund. >
Depending on a jurisdiction you live in, once you’ve made a profit or a loss investing in cryptocurrencies, you might need to include it in your tax report. In terms of taxation, cryptocurrencies are treated very differently from country to country. In the US, the Internal Revenue Service ruled that Bitcoins and other digital currencies are to be taxed as property, not currency. For investors, this means that accrued long-term gains and losses from cryptocurrency trading are taxed at each investor’s applicable capital gains rate, which stands at a maximum of 15 percent.
<>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. >
<>Paul Krugman, Nobel Memorial Prize in Economic Sciences winner does not like bitcoin, has repeated numerous times that it is a bubble that will not last and links it to Tulip mania. American business magnate Warren Buffett thinks that cryptocurrency will come to a bad ending. In October 2017, BlackRock CEO Laurence D. Fink called bitcoin an 'index of money laundering'. "Bitcoin just shows you how much demand for money laundering there is in the world," he said. >
<>The proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there's currently no standard form of it. Some cryptocurrencies use a combined proof-of-work/proof-of-stake scheme. >
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.
The rules that govern money market mutual funds permit the funds to buy only securities that mature in 397 days or less. At least 30% of the fund’s total assets must be invested in Weekly Liquid Assets, which can consist of cash, direct obligations of the U.S. government such as U.S. Treasury bills, certain other U.S. government agency debt that is issued at a discount and matures within 60 days or less, or securities that will mature or are payable within 5 business days. For taxable funds, at least 10% of the fund’s total assets must be invested in Daily Liquid Assets, which can consist of cash, direct obligations of the U.S. government, or securities that will mature or are payable within one business day. The remaining investments can be in longer-term issues, provided the overall weighted average maturity of the fund is 60 days or less.
<>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." >
<>Every transaction is a file that consists of the sender’s and recipient’s public keys (wallet addresses) and the amount of coins transferred. The transaction also needs to be signed off by the sender with their private key. All of this is just basic cryptography. Eventually, the transaction is broadcasted in the network, but it needs to be confirmed first. >
Ultrashort bond funds are mutual funds, similar to money market funds, that, as the name implies, invest in bonds with extremely short maturities. Unlike money market funds, however, there are no restrictions on the quality of the investments they hold. Instead, ultrashort bond funds typically invest in riskier securities in order to increase their return. Since these high-risk securities can experience large swings in price or even default, ultrashort bond funds, unlike money market funds, do not seek to maintain a stable $1.00 NAV and may lose money or dip below the $1.00 mark in the short term. Finally, because they invest in lower quality securities, ultrashort bond funds are more susceptible to adverse market conditions such as those brought on by the financial crisis of 2007–2010.
Central to the appeal and function of Bitcoin is the blockchain technology it uses to store an online ledger of all the transactions that have ever been conducted using bitcoins, providing a data structure for this ledger that is exposed to a limited threat from hackers and can be copied across all computers running Bitcoin software. Every new block generated must be verified by the ledgers of each user on the market, making it almost impossible to forge transaction histories. Many experts see this blockchain as having important uses in technologies such as online voting and crowdfunding, and major financial institutions such as JPMorgan Chase see potential in cryptocurrencies to lower transaction costs by making payment processing more efficient. However, because cryptocurrencies are virtual and do not have a central repository, a digital cryptocurrency balance can be wiped out by a computer crash if a backup copy of the holdings does not exist, or if somebody simply loses their private keys. At the same time, there is no central authority, government, or corporation that has access to your funds or your personal information.
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.

<>Basically, the Forex market is where banks, businesses, governments, investors and traders come to exchange and speculate on currencies. The Forex market is also referred to as the ‘Fx market’, ‘Currency market’, ‘Foreign exchange currency market’ or ‘Foreign currency market’, and it is the largest and most liquid market in the world with an average daily turnover of $3.98 trillion. >
<>In 1998, Wei Dai published a description of "b-money", characterized as an anonymous, distributed electronic cash system. Shortly thereafter, Nick Szabo described bit gold. Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo. >
On the borrowing end, after 10–20 years, the S&P 500 corporations become extremely accustomed to obtaining funds via these money markets, which are very stable. Initially, perhaps they only borrowed in these markets for a highly seasonal cash needs, being a net borrower for only say 90 days per year. They would borrow here as they experienced their deepest cash needs over an operating cycle to temporarily finance short-term build ups in inventory and receivables. Or, they moved to this funding market from a former bank revolving line of credit, that was guaranteed to be available to them as they needed it, but had to be cleaned up to a zero balance for at least 60 days out of the year. In these situations the corporations had sufficient other equity and debt financing for all of their regular capital needs. They were however dependent on these sources to be available to them, as needed, on an immediate daily basis.
<>1) Irreversible: After confirmation, a transaction can‘t be reversed. By nobody. And nobody means nobody. Not you, not your bank, not the president of the United States, not Satoshi, not your miner. Nobody. If you send money, you send it. Period. No one can help you, if you sent your funds to a scammer or if a hacker stole them from your computer. There is no safety net. >
<>The primary purpose of a money market fund is to provide investors a safe medium through which they can invest in easily accessible, secure, and highly liquid cash-equivalent debt-based assets using smaller investment amounts. It is a type of mutual fund characterized as a low-risk, low-return investment. Owing to the returns, investors may prefer parking substantial amounts of cash in such funds for the short term. However, money market funds are not suitable for long term investment goals, like retirement planning, as they don’t offer much capital appreciation. >
Cryptocurrencies' blockchains are secure, but other aspects of a cryptocurrency ecosystem are not immune to the threat of hacking. In Bitcoin's 10-year history, several online exchanges have been the subject of hacking and theft, sometimes with millions of dollars worth of 'coins' stolen. Still, many observers look at cryptocurrencies as hope that a currency can exist that preserves value, facilitates exchange, is more transportable than hard metals, and is outside the influence of central banks and governments.
<>There are currently more than 9,000 mutual funds that hold more than $16 trillion in assets. In part because of increased competition for those assets from lower-cost ETFs, mutual fund expenses continue to decline. Expense ratios averaged 0.63 percent in 2016 compared with 1.04 percent in 1996, according to the Investment Company Institute, though some funds levy additional management fees or sales charges that buyers should be aware of before purchasing. >
<>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. >
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.

One of the best ways to learn about forex is to see how prices move in real time and place some trades using fake money by using an account called a paper-trading account (so there is no actual financial risk to you). Several brokerages offer online or mobile phone app-based paper trading accounts that work exactly the same as live trading accounts, but without your own capital at risk.
