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.
“While it’s still fairly new and unstable relative to the gold standard, cryptocurrency is definitely gaining traction and will most certainly have more normalized uses in the next few years. Right now, in particular, it’s increasing in popularity with the post-election market uncertainty. The key will be in making it easy for large-scale adoption (as with anything involving crypto) including developing safeguards and protections for buyers/investors. I expect that within two years, we’ll be in a place where people can shove their money under the virtual mattress through cryptocurrency, and they’ll know that wherever they go, that money will be there.” – Sarah Granger, Author, and Speaker.
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.
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.

There are several different types of cryptocurrency wallets that cater for different needs. If your priority is privacy, you might want to opt for a paper or a hardware wallet. Those are the most secure ways of storing your crypto funds. There are also ‘cold’ (offline) wallets that are stored on your hard drive and online wallets, which can either be affiliated with exchanges or with independent platforms.
From the outset, money market funds fell under the jurisdiction of the SEC as they appeared to be more like investments (most similar to traditional stocks and bonds) vs. deposits and loans (cash and cash equivalents the domain of the bankers). Although money market funds are quite close to and are often accounted for as cash equivalents their main regulator, the SEC, has zero mandate to control the supply of money, limit the overall extension of credit, mitigate against boom and bust cycles, etc. The SEC’s focus remains on adequate disclosure of risk, and honesty and integrity in financial reporting and trading markets. After adequate disclosure, the SEC adopts a hands off, let the buyer beware attitude.
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.
We took a close look at over 70 financial institutions, including the largest U.S. banks based on assets, debit card volume, Internet search traffic and other factors; the nation’s largest credit unions, based on deposits as well as broad-based membership requirements; and other notable and/or emerging players in the industry. We rated them on criteria including annual percentage yields, minimum balances, fees, digital experience and more.
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.
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.
The one and only, the first and most famous cryptocurrency. Bitcoin serves as a digital gold standard in the whole cryptocurrency-industry, is used as a global means of payment and is the de-facto currency of cyber-crime like darknet markets or ransomware. After seven years in existence, Bitcoin‘s price has increased from zero to more than 650 Dollar, and its transaction volume reached more than 200.000 daily transactions.
Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC's complaint stated that Garza, through his companies, had fraudulently sold "investment contracts representing shares in the profits they claimed would be generated" from mining.
In the wholesale market, commercial paper is a popular borrowing mechanism because the interest rates are higher than for bank time deposits or Treasury bills, and a greater range of maturities is available, from overnight to 270 days. However, the risk of default is significantly higher for commercial paper than for bank or government instruments.
In response, on Friday, September 19, 2008, the U.S. Department of the Treasury announced an optional program to "insure the holdings of any publicly offered eligible money market mutual fund—both retail and institutional—that pays a fee to participate in the program". The insurance guaranteed that if a covered fund had broken the buck, it would have been restored to $1 NAV. The program was similar to the FDIC, in that it insured deposit-like holdings and sought to prevent runs on the bank. The guarantee was backed by assets of the Treasury Department's Exchange Stabilization Fund, up to a maximum of $50 billion. This program only covered assets invested in funds before September 19, 2008, and those who sold equities, for example, during the subsequent market crash and parked their assets in money funds, were at risk. The program immediately stabilized the system and stanched the outflows, but drew criticism from banking organizations, including the Independent Community Bankers of America and American Bankers Association, who expected funds to drain out of bank deposits and into newly insured money funds, as these latter would combine higher yields with insurance. The guarantee program ended on September 18, 2009, with no losses and generated $1.2 billion in revenue from the participation fees.
