Virtual currency contract yield

1. The leverage of the virtual contract is shown as the leverage stability of the revenue level of the legal currency: if you invest US $100, the revenue you can get is US $100 * the rise and fall of bitcoin * the fixed leverage ratio

assuming that the current price is 500usd / BTC, an investor can buy a BTC at the current price and the principal is 500usd. At this time, the investor can make 50 more BTC virtual contracts

at this time, if the price of BTC rises to US $750, or 50%, the investor's contract income is 3.3333 BTCs, which can be sold at the current price to get us $2500, and the income is five times of the principal investment

bitcoin futures provided by bitcoin exchanges are usually traded in bitcoin. Futures is opposite to spot. Spot is a commodity that can be paid and delivered at the same time. In fact, futures is not "goods", but an agreement (contract) - futures contract that promises to deliver "goods" (subject matter) at a future time. ZB fire coin, coin an

2. Contract trading is a general term for the trading of bitcoin futures contracts
in June 2013, 796 exchange took the lead in developing the bitcoin weekly delivery standard Futures - t + 0 two-way trading virtual commodity barter contract (contract trading) in the bitcoin instry
the emergence of contract trading ended the previous history that bitcoin could not be short, and opened the prelude to the development and prosperity of bitcoin derivatives market

3. It's not said that CPU can't dig. In the beginning, CPU was used to dig. However, with the in-depth study of mining algorithms, we found that the original mining was repeating the same work. As a general-purpose computing unit, CPU designed many moles such as branch prediction unit, register unit and so on, which did not help to improve the computing power at all
in addition, CPU is not good at parallel computing at all. It can perform more than ten tasks at most at one time. This is far from the fact that the graphics card has thousands of stream processors. The graphics card is too high, so we slowly develop the corresponding mining algorithm for the graphics card
taking BTC as an example, its basic algorithm principle is to take all transactions within 10 minutes as an input and add a random number. When all transactions within 10 minutes are added with your random number, a hash of sha256 is calculated. It's almost full of integer operations. It's just like a special design for a graphics card. The graphics card is very suitable for this kind of brainless algorithm. The more the number of stream processors, the better
as far as hash computing is concerned, it is almost all independent and concurrent integer computing, and GPU is designed and proced for this. Compared with the pitiful 2-8 threads of CPU and the astonishing length of control judgment and scheling branches, GPU can easily perform integer calculation concurrency of hundreds of threads (brainless brute force cracking without any judgment is the strength of a card)
OpenCL can make use of a large number of unified shaders on GPU chip, which can be used as resources for integer calculation. The resource of stream processor of a card is several times that of N card (the same level card)
but later, we found that the graphics card is still too weak, and the computing power can be greatly improved by directly using the ALU unit of large-scale ASIC stack. The computing power of the palm sized computing board is dozens of times that of the graphics card, so now bitcoin can't dig without a special ASIC miner
although a large number of interdependent and random memory access instructions are introced into the script algorithm used in the later LTC, when the footprint is large enough, a large number of cache failures will occur at the L2 level or even TLB level of GPU, resulting in more DRAM accesses, so as to weaken the advantage of ASIC / FPGA in integer operation performance compared with GPU, However, it is still targeted to develop mining machines. At present, only specialized mining machines can dig
however, the second generation of virtual currency (such as Eth and Zec) has absorbed the experience of the predecessors' blasted algorithms, and made more special optimization on the mining algorithm to prevent the occurrence of brainless operations. It has high requirements for video memory, so it can effectively resist the invasion of mining machines
because eth can only rely on graphics cards for mining, the rising price and shortage of graphics cards started in the second half of 2017. Many mine owners sold thousands of graphics cards to set up mining machines to mine these virtual currencies
over time, we all think that CPU can't mine, but in fact, the efficiency and benefit are too low.

4. Great wisdom is a real-time market display and trading system software
there are many functions, not only transaction information, but also other policies and company information that can be linked
you will know when you use it.
some shortcut keys are also very useful, such as those defined in the K-line state:
F1 is the transaction record of each order in time-sharing; F3 Shanghai index time-sharing chart, F4 Shenzhen index time-sharing chart
F6 select the sector of the stock pool; F7 current affairs information; F8 various K-line change display
f9f12 is transaction entrustment; If you are new to the stock market, it is recommended that you invest a small amount of money first,
wait until you have accumulated experience to a certain extent, and then do it.
I hope you can make small gains and big gains...

5. BTS is a base station transceiver, directly facing the user, the mobile phone's wireless signal is directly to the BTS. Generally, you can see an iron tower with a small house under it. BTS is there
a BSC is a base station controller. One BSC controls n BTS. BSC is usually in the Central Bureau (County Bureau or city Bureau). The signal received by BTS from mobile phone should be sent to BSC for processing
SDH is a transmission device, most of which are optical transmission devices
for example, BTS and BSC are two stations. The signals to be transmitted are people or goods. Optical fiber and optical cable are the road, and SDH transmission equipment is the car
in order to complete the signal transmission from BTS to BSC, both ends must have SDH transmission equipment.

6. Like okex's perpetual contracts, you can choose to open more or open less than 100 times.

7. Can't make money! Bitcoin has no practical value and can only be used for hype. They repeatedly emphasize how much money they can make a year and what the rate of return is, but they never mention how the profit returns come from.

8.

Monetary fund unit net value is always 1 yuan, no fees, if you buy 5000 yuan, that is to say, you now have 5000 copies of the fund

the income distribution of monetary fund is calculated as "per 10000 shares", for example, "0.4436 per 10000 shares" on a certain day, that is, the income that can be obtained for every 10000 shares of Monetary Fund on that day is 0.4436 yuan, and 5000 shares is 0.2218 yuan

another figure to understand the income situation is "7-day annualized rate of return", which refers to the average income of the last 7 days converted into the rate of return of one year“ "Earnings per 10000 shares" is your daily actual earnings, "7-day annualized yield" is a parameter to understand the long-term earning capacity of a monetary fund

the only dividend method of monetary fund is "dividend to investment", that is to say, the fund company will carry forward the accumulated income to your monetary fund share on a fixed day of each month. For example, if you now have 5000 shares of Huaxia cash with a face value of 1 yuan, and by the next month's income settlement date, your fund has made a profit of 50 yuan according to the income situation,

then the fund company will convert your income according to the face value of 1 yuan and add it to your fund share, that is to say, next month, you will have 5050 shares of Huaxia cash with a face value of 1 yuan

(of course, I'm just giving an example. How much money can be earned depends on the situation. Generally, the annual yield of monetary fund is 2% - 3%, which is a kind of financial management form with better liquidity when the deposit interest rate is relatively low.) Don't think of it as an investment

extended data:

monetary fund is a kind of open-end fund which gathers social idle funds, operates by fund managers and keeps funds by fund trustees. It is specialized in investing in money market tools with low risk. Different from other types of open-end funds, it has high security, high liquidity and stable returns, It has the characteristics of "quasi savings"

e to the emergence of digital currency, a new type of monetary fund appears in the field of Monetary Fund virtual Monetary Fund

investment field

monetary fund assets are mainly invested in short-term monetary instruments (generally within one year, with an average maturity of 120 days), such as treasury bonds, central bank bills, commercial bills, bank certificates of deposit, government short-term bonds, corporate bonds (with high credit rating), interbank deposits and other short-term securities

in fact, the investment scope of these money market funds are all varieties with high safety factor and stable income. Therefore, for many enterprises and indivials who want to avoid the risk of the securities market, money market funds are a natural haven, and they can usually obtain income higher than the interest of bank deposits, But the fund does not guarantee the security of the principal

But in fact, e to the nature of the fund, the loss of the principal of the monetary fund rarely occurs in reality. Generally speaking, monetary funds are regarded as cash equivalents.)

proct features

1. Principal security: most money market funds have the lowest risk among all kinds of funds, and the fund contract generally does not guarantee the security of principal, but in fact, e to the nature of the fund, the loss of principal rarely occurs in reality. Generally speaking, monetary funds are regarded as cash equivalents

Strong liquidity: the liquidity is comparable to that of current deposit. Fund trading is convenient, the time for funds to arrive at the account is short, and the liquidity is very high. Generally, funds can arrive at the account within one or two days after redemption. At present, fund companies have opened the immediate redemption business of Monetary Fund, which can arrive at the account on the same day

Higher yield: most money market funds generally have the yield level of national debt investment. Money market funds can not only invest in exchange repo and other investment tools that can be invested by ordinary institutions, but also enter the inter-bank bond and repo market and central bank bill market for investment. Their annual net return rate is generally higher than that of fixed deposit rate in the same period

Moreover, money market funds can avoid hidden losses. When there is inflation, the real interest rate may be very low or even negative. The money market fund can grasp the change of interest rate and the trend of inflation in time, and obtain stable and higher income

Low investment cost: Generally speaking, there is no service charge for buying and selling money market funds, and the subscription fee, subscription fee and redemption fee are all zero, so it is very convenient for funds to go in and out, which not only reces the investment cost, but also ensures the liquidity. The first subscription / subscription is 1000 yuan, and the second purchase is increased by 100 yuan

Dividend exemption: the face value of most money market funds is always 1 yuan, the income is calculated every day, and there is interest income every day. Investors enjoy compound interest, while bank deposits only enjoy simple interest. Monthly dividends are carried forward to fund shares, and dividends are exempt from income tax

9. The position of the contract will change with the change of the market. Assuming that the profit of the position reaches a certain amount, many positions will become long (short closing, because it is buying closing) or short (multi closing, selling closing). Therefore, the change of position depends on the change of market price and people's inner activities.
