<>While the country was once home to the world’s most active cryptocurrency exchanges, authorities banned the venues last year and have since moved to block access to platforms that offer exchange-like services. — Fortune, "China Is Said to be Cracking Down on a Cryptocurrency Loophole," 28 Feb. 2018 Bitcoin, however, has become the cryptocurrency standard operating much like U.S. dollar would operate in public currency markets, but in the crypto realm. — Michael C.

<>The validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way". For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority. >
To many retail investors, money market funds are confusingly similar to traditional bank demand deposits. Virtually all large money market funds offer check writing, ACH transfers, wiring of funds, associated debit and credit cards, detailed monthly statements of all cash transactions, copies of canceled checks, etc. This makes it appear that cash is actually in the individual’s account. With net asset values reported flat at $1.00, despite the market value variance of the actual underlying assets, an impression of rock solid stability is maintained. To help maintain this impression, money market fund managers frequently forgo being reimbursed legitimate fund expenses, or cut their management fee, on an ad hoc and informal basis, to maintain that solid appearance of stability.
Institutional money funds are high minimum investment, low expense share classes that are marketed to corporations, governments, or fiduciaries. They are often set up so that money is swept to them overnight from a company's main operating accounts. Large national chains often have many accounts with banks all across the country, but electronically pull a majority of funds on deposit with them to a concentrated money market fund.
<>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.
