blockchain blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism and cryptocurrency algorithm. Is a shared distributed ledger in which transactions are permanently recorded through additional blocks
2, block - block
in the bitcoin network, data will be permanently recorded in the form of files, which we call blocks. A block is a set of records for some or all of the latest bitcoin transactions and is not recorded by other previous blocks
3. Node -- a of the ledger operated by the participants of the blockchain network
Decentralization is a phenomenon or structure, which can only appear or exist in a system with many nodes or in a group with many indivials. The influence between nodes will form nonlinear causality through the network5. Consensus mechanism
consensus mechanism is to complete the verification and confirmation of the transaction in a very short time through the voting of special nodes; For a transaction, if several nodes with unrelated interests can reach a consensus, we can think that the whole network can also reach a consensus
6. POW -- proof of work refers to how much money you get depends on the amount of work you contribute to mining. The better the performance of the computer, the more money you will be given

Privatekey - private key
a private key is a string of data that allows you to access a token in a specific wallet. As cryptocurrency, they are hidden except for the owner of the address
14. Publickey -- public key

15, miner
try to create a block and add it to the computing device or software on the blockchain. In a blockchain network, when a new effective block is created, the system will automatically give the block creator (miner) a certain number of tokens as a reward
16. The mine pool is a fully automatic mining platform, which enables mining machines to contribute their computing power to mine together to create blocks, obtain block rewards, and distribute profits according to the proportion of computing power contribution (that is, mining machines access the mine pool - provide computing power - obtain income)
17, public chain
fully open blockchain, refers to anyone can read, anyone can send transactions and transactions can be effectively confirmed, people all over the world can participate in system maintenance, anyone can read and write data through transactions or mining
18. Private chain
write permission is only for the blockchain of a certain organization or a specific few objects. Read permission can be open to the outside world or restricted to any extent
19, alliance chain
consensus mechanism is a blockchain jointly controlled by several designated institutions
20, side chain
wedged side chains technology, which will realize the transfer of bitcoin and other digital assets between multiple blockchains, which means that users can access the new cryptocurrency system when they use their existing assets
21, cross chain technology
cross chain technology can be understood as a bridge connecting the blockchains, and its main application is to realize atom transaction, asset conversion, information exchange within the blockchain, or solve Oracle problems among the blockchains
22. The hard fork
blockchain has permanent divergence. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually the hard fork will occur
23, soft forking
when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, which will lead to temporary forking
24, hash -- hash value
generally translated as "hash", but also directly transliterated as "hash". In short, it is a function that compresses messages of any length to a message digest of a fixed length
25, main chain
the word "main chain" comes from the main network (, relative to the test network), that is, the officially online and independent blockchain network

What is leverage
leverage trading, as the name suggests, is to use small amount of funds to invest several times the original amount, in order to obtain multiple returns or losses relative to the fluctuations of the investment object
Leverage is a common financial transaction system, namely margin system
Leverage trading is also called virtual trading and deposit trading. That is to say, investors use their own funds as guarantee to enlarge the financing provided by banks or brokers to carry out foreign exchange transactions, that is, to enlarge the trading funds of investors. The proportion of financing is generally decided by banks or brokers. The larger the proportion of financing is, the less capital customers need to pay
leverage trading operation process:
1. Take BTC / usdt as an example, if the platform supports up to three times leverage
when judging that the price of bitcoin will rise from 10000 usdt to 20000 usdt, if you have 10000 usdt of principal, you can borrow up to 20000 usdt from the platform. Use 30000 usdt to buy 3btc at the price of 10000 usdt and sell it at the price of 20000 usdt, with a profit of 3btc * (20000-10000) = 30000 usdt
2. Take BTC / usdt as an example, if the platform supports up to 3 times leverage
when it is judged that the price of bitcoin will drop from 20000 usdt to 10000 usdt, with a principal of 10000 usdt (0.5btc), you can borrow 1btc from the platform, sell one bitcoin at 20000 usdt, and buy it at 10000 usdt, making a profit of 10000 usdt
if you only trade with your own funds, you can only buy low and sell high, not short
3. Calculation method of leverage lending rate:
from the time of applying for leverage, the interest will be calculated as 24 hours in less than 24 hours, and the loan funds and interest will be returned when the leverage is returned
4, the risk of leverage Trading:
leverage makes use of less capital to realize the possibility of obtaining greater returns. But if the wrong direction of the transaction is judged, the loss will also be enlarged year on year. Therefore, ordinary traders try to avoid the high leverage of heavy trading, to prevent the occurrence of burst positions or even through positions
(1) reasonable use of leverage ratio and control of position (2) stop profit and loss timely and close positions spontaneously (3) margin should be added in time to ensure that the ratio of total assets to leverage is greater than 110%extended data
related functions of leverage Trading:
1. Loan account:
each loan transaction pair corresponds to a loan account. For example, ETH / BTC will correspond to an eth / BTC loan account (including two sub accounts of Eth and BTC)
users can transfer Eth and BTC monetary assets in the transaction account to eth / BTC lending account; Eth / BTC loan account can be applied for loan in two types of currency assets: Eth and BTC
2. Fund transfer:
users can't recharge to the loan account directly for the time being, so they can transfer the funds from the transaction account to the loan account by fund transfer
(1) when the user borrows, the part of the loan account with a risk rate higher than 200% can be transferred out to the transaction account
(2) when the user has no loan, all the available funds in the account can be transferred out to the transaction account
3. Apply for loan:
the user enters the loan management and selects the loan account to apply for loan assets. The amount of digital currency that the user can apply for loan depends on the account principal and platform leverage ratio. The maximum amount of loan that the user can apply for is net asset conversion (BTC) × Multiple - 1) - borrowed assets
for example, if the maximum leverage ratio of the platform is 3 times, the number of digital currencies that users can borrow is 2 times of the principal

however, Lizzie Lo said that after a round of slump,
it noticed that usdt, a stable currency, had a large premium as a ticket for investment in the currency circle, which meant that there was a lot of money on the sidelines. In the medium and long term, it believes in the consensus of bitcoin, and the downward adjustment only gives opportunities for traditional funds that had not entered the market

Yi Gang: at present, there is no timetable for its launch. The goal is to replace part of M0. It is worth noting that recently, it was reported in the market that "the Central Bank of China will issue digital currency within 80 days". At a news conference yesterday (September 24), Yi Gang, governor of the people's Bank of China, said that there is no timetable for the introction of digital currency Yi Gang said:I would like to say a few points about digital currency. First, the people's Bank of China has been studying digital currency since 2014. We have a digital currency Research Institute and a special team, and we have made positive progress. We combine the central bank's digital currency and electronic payment tools, so it is called a package of digital currency and electronic payment
Second, what are the goals of digital money and electronic payment in the future? The goal is to replace a part of M0, that is, to replace a part of cash. It does not mean to replace M1 or m2 Third, the future framework of our digital currency is a two-tier operation system of the central bank and commercial banks, which will not change the current money supply path and system, so as to fully mobilize the enthusiasm of the marketFourth, we will adhere to the centralized management, do not presuppose the technical route in the research and development work, we can choose the best in the market through fair competition, we can consider the blockchain technology, we can also adopt the new technology evolved from the existing electronic payment, fully mobilize the enthusiasm and creativity of the market, we have also set up a mechanism compatible with the incentive mechanism of market institutions. As for when you ask, we don't have a timetable. I think there will be a series of research, testing, pilot, assessment and risk prevention. Especially if digital currency is used across borders, there will be a series of regulatory requirements such as anti money laundering, anti terrorist financing, anti tax haven and "know your customer"

on September 4, 2017, the people's Bank of China and other seven ministries and commissions issued the "notice on preventing the financing risk of token issuance", which cleaned up the ICO and virtual currency trading venues. The scale of domestic virtual currency transactions decreased significantly, effectively avoiding the impact of virtual currency prices on China's financial market.
the so-called option is that investors trade a certain commodity, but they do not need to actually hold the commodity. They only need to pay a small transaction fee to the exchange to obtain the trading authority of the subject matter within a certain period of time, and they can trade in both directions
in terms of operation, if you are expected to be bullish, you will buy up and if you are expected to be bearish, you will buy down. The calculation of profit is the same as that of spot
to take a simple example, Xiaoming predicted that eth would rise sharply in the short term, so he spent 50usdt to buy 100 1-hour eth call options in the exchange, and one hour later eth rose 10usdt, then Xiaoming's profit was 100x10-50 = 950usdt
If Xiaoming bought the call options, and eth fell 10usdt in the reverse one hour later, Xiaoming's loss was only 50usdt of the call options, In addition, there is no need to bear the loss risk caused by the substantial fluctuation of spot and futures contracts
in short, the option is a kind of small and broad investment proct, only need to pay a little transaction fee, can obtain the right of proct return in a certain period, and the risk loss is only the transaction fee
at present, bitoffer adopts the American option trading method, which can grasp the market at any time without waiting for the closing time. It is easier to control the risk. If you have certain trading experience and market sensitivity, trading eth options is relatively simple.
one is that the futures customer still owes money to the futures exchange after closing the position, that is, the floating profit and loss of the account is equal to or greater than the total capital of the account, that is, the customer's equity is less than or equal to 0, The margin on the account can no longer maintain the original contract. This kind of margin "return to zero" caused by forced position closing e to insufficient margin is commonly known as "position explosion", and the meaning of "position penetration" is the same as "position explosion"
at present, the phenomenon of position explosion is basically not allowed in China. There is a limit on the rise and fall in China. When the margin is kept below, futures companies will automatically close their positions. Among the Hang Seng Index Futures in Hong Kong, the Hang Seng index is a 4-hour trading system. The next day, there may be a large short jump or high jump, which will lead to the reversal of the position. As soon as the market opens, the position will explode, or even be negative. A negative number is the money owed to the futures trading company because the futures brokerage company pasted the money to the futures exchange to close the customer's position. For example 1: data example 4: before the opening of trading on August 11, the customer did not give the margin that should be added to the futures company, and the stock index futures contract in September fell by 90 points, opened at 1060 points and continued to fall. The futures brokerage company forced the closing of 15 long positions of the client, with the transaction price of 1055 points
3. Foreign exchange position explosion: foreign exchange position explosion refers to the situation in which the customer's equity in the investor's margin account is negative under some special conditions. When the market changes greatly, if most of the funds in the margin account of investors are occupied by trading margin, and the trading direction is opposite to the market trend, it is easy to burst e to the leverage effect of margin trading. If the burst leads to a deficit and is caused by investors, investors need to make up the deficit, otherwise they will face legal recourse.
