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.
<>The types of debt securities held by money market mutual funds are required by federal regulation to be very short in maturity and high in credit quality. All money market funds comply with industry-standard regulatory requirements regarding the quality, maturity, liquidity, and diversification of the fund’s investments. Investments can include short-term U.S. Treasury securities, federal agency notes, Eurodollar deposits, repurchase agreements, certificates of deposit, corporate commercial paper, and obligations of states, cities, or other types of municipal agencies—depending on the focus of the fund. >

Brunnermeir,Deciphering the 2007-08 Liquidity and Credit Crunch, Journal of Economic Perspectives (May, 2008)(arguing that investment banks reliance on commercial paper and repo markets had increased over the last 3 years.

<>The world then decided to have fixed exchange rates that resulted in the U.S. dollar being the primary reserve currency and that it would be the only currency backed by gold, this is known as the ‘Bretton Woods System’ and it happened in 1944 (I know you super excited to know that). In 1971 the U.S. declared that it would no longer exchange gold for U.S. dollars that were held in foreign reserves, this marked the end of the Bretton Woods System. >
<>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. >
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.
