Cryptocurrencies are systems that allow for the secure payments of online transactions that are denominated in terms of a virtual "token," representing ledger entries internal to the system itself. "Crypto" refers to the fact that various encryption algorithms and cryptographic techniques, such as elliptical curve encryption, public-private key pairs, and hashing functions, are employed.
Many people believe that cryptocurrencies are the hottest investment opportunity currently available. Indeed, there are many stories of people becoming millionaires through their Bitcoin investments. Bitcoin is the most recognizable digital currency to date, and just last year one BTC was valued at $800. In November 2017, the price of one Bitcoin exceeded $7,000.
In 1971, Bruce R. Bent and Henry B. R. Brown established the first money market fund. It was named the Reserve Fund and was offered to investors who were interested in preserving their cash and earning a small rate of return. Several more funds were shortly set up and the market grew significantly over the next few years. Money market funds are credited with popularizing mutual funds in general, which until that time, were not widely utilized.
To understand the revolutionary impact of cryptocurrencies you need to consider both properties. Bitcoin as a permissionless, irreversible, and pseudonymous means of payment is an attack on the control of banks and governments over the monetary transactions of their citizens. You can‘t hinder someone to use Bitcoin, you can‘t prohibit someone to accept a payment, you can‘t undo a transaction.
Interest rates determine how much interest your money market account earns. The more money you have in your money market account and the higher interest rate you’re earning, the more money you’ll earn on your money in this account. When the Federal Reserve raises or lowers the federal funds rate, its benchmark rate, that tends to affect the yields on money market accounts. Since December 2015, the Fed has raised rates nine times, which has helped some money market account yields increase.
Government Normally at least 99.5% of the fund’s total assets are invested in cash, U.S. government securities and/or repurchase agreements that are collateralized fully (i.e., collateralized by cash or government securities)—including at least 80% in U.S. government securities and repurchase agreements for those securities. Certain issuers of U.S. government securities (e.g., “Government-Sponsored Enterprises” such as Fannie Mae, Freddie Mac, and the Federal Home Loan Banks) are sponsored or chartered by Congress, but their securities are neither issued by nor guaranteed by the U.S. Treasury.
