Bitcoin quant bitcoin quantitative fund
when it comes to the big three of traditional contracts, I have to mention bitmex. This old exchange was once the largest bitcoin contract trading platform in the world. With the advantages of good market depth and low transaction fees, it has long been at the top of the global exchanges only by contract trading. On the evening of May 19, bitmex suddenly went down, and investors could not operate normally for more than an hour. The last outage occurred two months ago. Although bitmex is still in the leading camp in the field of contract exchanges, its aura is much dimmer than at its peak. Repeated downtime and successive court cases have made many users suspicious of the platform and added uncertainty to the future of the platform
according to the latest data from skew, a cryptocurrency derivatives analysis company, bitmex ranked fourth with us $2.17 billion in the 24-hour BTC contract trading volume of the exchange, followed by fire coin, okex and coin an, with trading volumes of US $4.08 billion, US $3.93 billion and US $35.4 respectively, among which fire coin ranked first was nearly twice as high as bitmex. It can be seen that the performance of the old contract exchange's hot money and okex is still good. In just three months, the online perpetual contract of Huo coin won the first place in trading volume, which is closely related to the global compliance, mine pool, public chain, HT and other invisible values behind Huo coin group. On the other hand, however, when faced with the "312 exam", Huo coin and okex did not seem to go smoothly. For a while, problems such as pin insertion, downtime, network cable pulling, and inability to close positions swarmed in, and even the headquarters rights protection incident occurred. Like bitmex, customers of both exchanges are questioning whether this is a manifestation of "shoplifting"? In the face of extremely high trading volume and accumulated instry reputation over the past few years, how should Xiaosan choose
in September 2019, Jex, the cryptocurrency derivatives platform, was acquired by the security capital, and a / b double contracts were launched in parallel. Almost at the same time, bitmex's official twitter also targeted "plagiarism" at coin an. From open margin trading to futures and options, currency security is following the path of contracts. It seems that the way of currency security entering the contract is not smooth: a series of scandals, such as deliberate pin insertion, K-line optimization and early position explosion, also broke out. But these still can't stop coin an from taking a share in the traditional contract giant's trading volume
of course, good depth, large user base and strong professionalism are the advantages of the first-line mainstream exchanges. The other side of the coin, such as bitmex's too professional user interface, has turned away many new retail investors and Xiao users. At the same time, KOL, big V and local communities, which have strong capacity to bring volume, resolutely join in the arms of emerging exchanges such as bybit and bitge e to low commission rebate and low handling charges
all along, bybit's image in the circle is more like an "overseas player". According to official data, most users of bybit are located in Europe, with only 20% in Asia. In addition, bybit performs well in proct experience and other aspects, and the proct interface is single and clear, which can give users a better visual experience. Recently, the relevant person in charge of bybit said that it is necessary to vigorously develop the domestic market, but at present, there are few bybit contract varieties, and the Chinese market contract market competition is white hot, and the customer demand is diversified. If it wants to sink, I wonder if it will be acclimatized? Let's see
bitget is starting to make its mark in the contract instry this year. Because of its strong user experience and customer service, it has attracted a large number of Xiao users, and has good trading depth, so it is called "black horse of contract trading" in the circle. Recently, the newly launched one click merchandising proct is widely praised for its focus on solving the two-way pain points of users and traders. It is especially suitable for small white users and can play contracts without threshold. According to the evaluation on social network, bitget didn't go down in the two extreme markets of last year's "9.25" and this year's "3.12". The drawback is that although the positive and negative currencies are complete, before bitget only had one warehouse by one, not the whole warehouse, some users will not be used to it. Fortunately, now this function is online. It's a good choice
emerging exchange FTX was established in 2019. According to skew, a well-known data website, the daily trading volume of eth futures jumped to a record high of US $245 million on February 28, an increase of 51% compared with us $162 million on February 25. Behind the gorgeous trading data, the CEO of FTX fell into the scandal of misappropriating the assets of exchange customers, which also dragged FTX into a negative quagmire. According to the relevant data, most of FTX customers are from quantitative organizations, and the operation interface also stays at the PC side. At present, the app version has not been launched. For most domestic retail investors who are used to mobile Internet, inconvenient use is one of the biggest problems.
value scale = when you buy something, a bottle of water is one yuan. The one yuan here is the currency of concept, and no one needs to take out one yuan and put it there to tell you that this thing is one yuan
means of circulation = when you want to own this bottle of water, you must give the seller a dollar, instead of just saying "I'll give you a dollar ~"
the function of storage is to store valuable currency (such as gold and silver) at home for future appreciation or use (because it is valuable and not afraid of depreciation). Strictly speaking, RMB is bank notes, a kind of credit currency = no intrinsic value (just a piece of paper) but only use value (its value is guaranteed by government revenue), so RMB cannot be used as a storage means (in case of serious inflation or regime change, it is a pile of waste paper)
means of payment = standard of deferred payment = unilateral transfer of currency. For example, the money that others owed you a few days ago was paid back today.
money performs the function of value measurement, which is to show the value of all commodities as a certain amount of money. This is because money itself is a commodity and has value. All kinds of goods are the condensation of social labor with the same quality, so labor time is the intrinsic value measure of goods. This kind of intrinsic value can be compared, but it can't show itself. In the process of commodity exchange, when money performs the function of value measurement to measure the value of other commodities, and makes all kinds of commodity values behave as a certain amount of money, money becomes the external manifestation of commodity value
2. Means of circulation: in commodity circulation, money serves as the medium of commodity exchange
the circulation function of money is developed in commodity exchange. Before the emergence of money, commodity exchange took the form of direct exchange. After the emergence of money, it becomes the commodity circulation with money as the medium, which makes the direct commodity exchange into two processes. Any commodity procer must first sell goods for money (w-g), and then use money to buy back the needed goods (G-W). In the commodity exchange composed of these two processes, money acts as the medium of exchange activities. The function of this kind of medium commodity exchange is the function of currency circulation means
3. Storage means: the function of money withdrawal from circulation as an independent value form and the general representative of social wealth
the function of money storage means is graally improved in practice. At first, it was shown as simple money storage. The procer changed surplus procts into money in order to save his surplus procts with money. With the development of commodity proction, in order to make it easy for commodity procers to buy commodities that can maintain proction and life at any time, money storage is mainly manifested as the storage of exchange value. When commodity circulation expands to all fields, the one who owns money can buy everything he needs. At this time, money storage is manifested as money storage of social power. But the money storage for any purpose must be the enough money with value entity
4. Means of payment: the function of money as an independent form of value in unilateral movement
the function of money as a means of payment was initially generated to meet the needs of commodity proction and exchange. Because the proction cycle of different commodities is different, and the distance from the place of origin to the place of sale is different, in order to ensure the continuous reproction process, some commodity procers need to sell goods on credit. When the debt is settled on the appointed date, money has the function of payment means. Later, with the development of commodity exchange and credit economy, the function of money as a means of payment has become increasingly common, not only beyond the field of commodity circulation, but also into people's daily life, such as for the payment of government rent, rent, wages, taxes and so on
5. World currency -- the currency as a general equivalent in the world market
with the emergence and development of international exchanges, currency has the function of world currency when it circulates in the world market. In addition to the function of value measurement, the world currency also performs the following functions: as a means of purchase, it is used internationally to purchase foreign goods; As a general means of payment, it is used to pay international debts, interest and other unproctive payments to balance the international balance of payments; As the representative of social wealth, it is used to pay war reparations, export monetary capital, etc., and transfer from one country to another.
explanation
"bad money expels good money" means that when a country circulates two kinds of money with different real value but unchanged legal price at the same time, the money with high real value (good money) is bound to be melted, collected or exported and withdraw from the circulation field, while the money with low real value (bad money) fills the market instead
for example
in the 16th century England, precious metals were not enough for coinage, so other metals had to be added to the newly minted coins. Therefore, there were two kinds of currencies in the market at that time, one was the currency without impurities, the other was the currency added to other metals. Although the legal value of the two currencies is equal, people can identify them, store the money without impurities, and trade the money with impurities. Therefore, the good money on the market is graally stored and reced circulation, leaving only the bad money in the market Good money here refers to money without impurities.)
