As of February 2018, the Chinese Government halted trading of virtual currency, banned initial coin offerings and shut down mining. Some Chinese miners have since relocated to Canada. One company is operating data centers for mining operations at Canadian oil and gas field sites, due to low gas prices. In June 2018, Hydro Quebec proposed to the provincial government to allocate 500 MW to crypto companies for mining. According to a February 2018 report from Fortune, Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity. Prices are contained because nearly all of the country's energy comes from renewable sources, prompting more mining companies to consider opening operations in Iceland.
A money market fund is a type of fixed income mutual fund with very stringent maturity, credit quality, diversification, and liquidity requirements intended to help it achieve its goals of principal preservation and daily access for investors. Customers should determine when picking a money market fund that its characteristics align with their investment objectives and strategy.
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.
Take the money on your bank account: What is it more than entries in a database that can only be changed under specific conditions? You can even take physical coins and notes: What are they else than limited entries in a public physical database that can only be changed if you match the condition than you physically own the coins and notes? Money is all about a verified entry in some kind of database of accounts, balances, and transactions.
Industries generally need long-term loans, which are provided in the capital market. However, the capital market depends upon the nature of and the conditions in the money market. The short-term interest rates of the money market influence the long-term interest rates of the capital market. Thus, money market indirectly helps the industries through its link with and influence on long-term capital market.
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.
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.
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.
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.
Under the provisions, a money fund mainly invests in the top-rated debt instruments, and they should have a maturity period under 13 months. The money market fund portfolio is required to maintain a weighted average maturity (WAM) period of 60 days or less. This WAM requirement means that the average maturity period of all the invested instruments taken in proportion to their weights in the fund portfolio should not be more than 60 days. This maturity limitation is done to ensure that only highly liquid instruments qualify for investments, and the investor’s money is not locked-in long maturity instruments that can mar the liquidity.
These changes require prime institutional money market funds to “float their NAV” and no longer maintain a stable price. The regulations also provide non-government money market fund boards with new tools to address runs. Retail and U.S. government money market funds were allowed to maintain the stable $1 per share policy. These reforms took effect in 2016.
An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017. Popular favorites of cryptocurrency miners such as Nvidia's GTX 1060 and GTX 1070 graphics cards, as well as AMD's RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock. A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.
If this sounds similar to banks’ high-yield savings accounts or money market accounts, it is. The largest difference lies in the ability for yields on money market mutual funds to rise proportionately with interest rates. For example, as interest rates have risen, the yields on most bank money market accounts (which are set by the banks themselves) have stayed relatively flat, while money market mutual fund yields have increased.
