Around the same time, Nick Szabo, a computer scientist who now blogs about law and the history of money, was one of the first to imagine a new digital currency from the ground up. Although many consider his scheme, which he calls "bit gold", to be a precursor to Bitcoin
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.
The “requesting a transaction” means you want to transfers some coins (let’s say bitcoin) to someone else. When you make the request the request is broadcasted to all the nodes. Then the nodes verify that (from all the history of transactions) you are not double spending your coins. When verified successfully the transaction is added in a block which is then mined by a miner. When the block is mined, your transaction is confirmed and the coins are transfered.
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.
While it’s very easy to buy Bitcoins - there are numerous exchanges in existence that trade in BTC - other cryptocurrencies aren’t as easy to acquire. Although, this situation is slowly improving with major exchanges like Kraken, BitFinex, BitStamp and many others starting to sell Litecoin, Ethereum, Monero, Ripple and so on. There are also a few other different ways of being coin, for instance, you can trade face-to-face with a seller or use a Bitcoin ATM.
Over time, money market fund "depositors" felt more and more secure, and not really at risk. Likewise, on the other end, corporations saw the attractive interest rates and incredibly easy ability to constantly roll over short term commercial paper. Using rollovers they then funded longer and longer term obligations via the money markets. This expands credit. It’s also over time clearly long-term borrowing on one end, funded by an on-demand depositor on the other, with some substantial obfuscation as to what is ultimately going on in between.
On 21 November 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USDT from their primary wallet. The company has 'tagged' the stolen currency, hoping to 'lock' them in the hacker's wallet (making them unspendable). Tether indicates that it is building a new core for its primary wallet in response to the attack in order to prevent the stolen coins from being used.
The first money market mutual fund to break the buck was First Multifund for Daily Income (FMDI) in 1978, liquidating and restating NAV at 94 cents per share. An argument has been made that FMDI was not technically a money market fund as at the time of liquidation the average maturity of securities in its portfolio exceeded two years. However, prospective investors were informed that FMDI would invest "solely in Short-Term (30-90 days) MONEY MARKET obligations". Furthermore, the rule restricting which the maturities which money market funds are permitted to invest in, Rule 2a-7 of the Investment Company Act of 1940, was not promulgated until 1983. Prior to the adoption of this rule, a mutual fund had to do little other than present itself as a money market fund, which FMDI did. Seeking higher yield, FMDI had purchased increasingly longer maturity securities, and rising interest rates negatively impacted the value of its portfolio. In order to meet increasing redemptions, the fund was forced to sell a certificate of deposit at a 3% loss, triggering a restatement of its NAV and the first instance of a money market fund "breaking the buck".
