Foreign digital currency futures investment institutions
in December 2018, NASDAQ announced its investment in the cryptocurrency exchange erisx. Compared with bakkt, although behind erisx are Nasdaq, CBOE, CME, fidelity and TD Ameritrade, one of the largest Internet Securities Companies in the United States, they are relatively unknown. But it was approved by the US Commodity Futures Trading Commission earlier than bakkt to launch compliant bitcoin futures
NYSE and NASDAQ are competing for the first place, and the London Stock Exchange (LSE), the largest stock exchange in Europe, is not willing to fall behind. In January 2019, the London Stock Exchange Group (lseg) announced that it would provide technology drive for atom asset exchange (AAX exchange) to enter the digital money market in a "curve entry" way.
digital currency is abbreviated as digiccy, which is the abbreviation of "digital currency" in English, and is an alternative currency in the form of electronic currency. Both digital gold coin and cryptocurrency belong to digiccy
digital currency is a kind of unregulated and digital currency, which is usually issued and managed by developers and accepted and used by members of specific virtual communities. The European Banking authority defines virtual currency as a digital representation of value, which is not issued by the central bank or authorities, nor linked with legal currency. However, because it is accepted by the public, it can be used as a means of payment, or it can be transferred, stored or traded in electronic form
Futures:
futures, whose English name is futures, is totally different from spot. Spot is actually tradable goods (commodities). Futures are mainly not goods, but standardized tradable contracts based on certain popular procts such as cotton, soybean, oil, and financial assets such as stocks and bonds. Therefore, the subject matter can be a commodity (such as gold, crude oil, agricultural procts) or a financial instrument
the days of futures settlement can be one week later, one month later, three months later, or even one year later
a contract or agreement to buy or sell futures is called a futures contract. The place where futures are traded is called the futures market. Investors can invest or speculate in futures
foreign exchange:
foreign exchange, English name is foreign currency, which is the creditor's rights that the monetary Administration (central bank, monetary management institution, foreign exchange stabilization fund and the Ministry of Finance) can use in the event of balance of payments deficit in the form of bank deposits, treasury bonds of the Ministry of finance, long-term and short-term government securities, etc
it includes foreign currency, foreign currency deposits, foreign currency securities (government bonds, treasury bonds, corporate bonds, stocks, etc.), and foreign currency payment certificates (bills, bank deposit certificates, postal savings certificates, etc.)
as of 2015, China ranked first in the world in terms of foreign exchange reserves. But the United States, Japan, Germany and other state-owned private foreign exchange reserves, the country's overall foreign exchange reserves are much higher than China.

antimony metal element, element symbol sb, atomic number 51. It is a kind of metalloid with metallic luster and mainly exists in the sulfide mineral stibnite (Sb2S3) in nature. It is known that antimony compounds were used as cosmetics in ancient times. [1] metallic antimony was also recorded in ancient times, but it was mistaken for lead at that time. Antimony was known to be a chemical element around the 17th century
silver white, glossy, hard and brittle metal (often made into rod, block, powder and other shapes). It has a scaly crystal structure. It graally loses luster in humid air and burns into white antimony oxide in strong heat. It is soluble in aqua regia and concentrated sulfuric acid. The relative density is 6.68, the melting point is 630 ℃, the boiling point is 1635 ℃, and the atomic radius is 1.28-197;, Electronegativity 2.2
since the end of the 20th century, China has become the largest procer of antimony and its compounds in the world, and most of them are proced in the tin mines in Lengshuijiang City, Hunan Province (note, they are not called antimony mines). The instrial process of antimony is roasting first, then recing with carbon at high temperature, or directly recing stibnite with metallic iron
lead antimony alloy plates used in lead-acid batteries. Antimony alloys with lead and tin can be used to improve the properties of welding materials, bullets and bearings. Antimony compounds are important additives of chlorine and bromine containing flame retardants, which are widely used. Antimony is also widely used in emerging microelectronic technology, such as amd graphics card manufacturing
antimony is a gray metal with silver luster, and its Mohs hardness is 3. Therefore, pure antimony can not be used to make hard objects: Guizhou Province of China issued antimony coins in 1931, but because antimony is easy to wear and tear, it lost a lot in circulation
antimony is a nitrogen group element with electronegativity of 2.05. According to the periodic law of elements, its electronegativity is larger than that of tin and bismuth, and smaller than that of tellurium and arsenic. Antimony is stable in air at room temperature, but it can react with oxygen to form antimony trioxide when heated[ 2] Antimony does not react with acid under normal conditions
at present, there are four kinds of allotropes of antimony, one kind of stable metallic antimony and three kinds of metastable antimony (explosive antimony, black antimony and yellow antimony). Metallic antimony is a fragile silver white lustrous metal. When the molten antimony is cooled slowly, it will form a cubic crystal, which is heteromorphic with the gray allotrope of arsenic. The rare explosive antimony can be made by electrolysis of antimony trichloride. If it is scratched with sharp instruments, an exothermic chemical reaction will occur, which will emit white smoke and form metallic antimony. If you grind it in a mortar with a pestle, it will explode violently. Black antimony is formed by the rapid cooling of metallic antimony vapor. Its crystal structure is the same as red phosphorus and black arsenic. It is easy to be oxidized or even spontaneous combustion in oxygen. When the temperature drops to 100 ℃, it graally transforms into a stable crystal. Yellow antimony is the most unstable one, which can only be obtained by the oxidation of hydrogen antimonide at - 90 ℃. Under the action of this temperature and ambient light, the metastable allotrope will be transformed into a more stable black antimony[ 3]
the structure of antimony is a layered structure (space group: R3m No. 166), and each layer contains a connected folded six membered ring structure. The nearest and the next nearest antimony atoms form a deformed octahedron, and the three antimony atoms in the same bilayer are slightly closer than the other three. The relatively close distance makes the density of antimony metal reach 6.697g/cm, but the weak bonding between layers also makes it very soft and fragile

with the rise of blockchain technology, the encryption of blockchain technology can provide solutions for the protection of personal information. Blockchain technology can store personal information in a distributed way to avoid the security risks faced by a single server.
According to reports, coinbase, the largest cryptocurrency exchange in the United States, is also listed, which is also a milestone event of digital currency. As soon as the exchange opened, its trading volume reached tens of billions. Affected by this, bitcoin also set a new record. The CEO of coinbase also said that the exchange is completely free. His purpose is to achieve economic freedom all over the world, so that everyone will get his share of the money, and also hope that everyone in the world can live a better life. I have to say that the starting point of this is good, but no one does not cut leeks, so we should be careful
digital currency has the following characteristics: low transaction cost, fast transaction speed and strong anonymity. Let's look at the transaction cost of digital currency first. As we all know, traditional transfer and remittance all need to pay a certain fee to a third party, but digital currency breaks this transaction rule and does not need to pay a fee to a third party. The transaction speed of digital currency is very fast. At present, the block chain technology is used in digital currency. The block chain has the characteristics of decentralization, and does not need any centralized organization to process data. Therefore, digital currency belongs to the decentralized transaction method, and its transaction speed is much faster than the traditional transaction with centralized organization before. After all, without a third-party organization, it is more efficient
