How much is bitcoin contract transaction

1.

Similar to futures contract, it is a trading method proposed by bitstar

the leverage of bitcoin virtual contract is shown as the leverage stability of the revenue level of legal currency: if you invest US $100, the revenue you can get = 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

extended data:

futures contract is an agreement that the buyer agrees to receive certain assets at a specific price after a specified period of time, and the Seller agrees to deliver certain assets at a specific price after a specified period of time. The price that both parties agree to use in future trading is called futures price

the specified date on which both parties must conct transactions in the future is called settlement date or delivery date. The assets agreed to be exchanged by both parties are called "subject matter". If an investor gains a position in the market by buying a futures contract (i.e. agreeing to buy at a future date), it is called long position or long in futures

On the contrary, if the position obtained by investors is to sell the futures contract (i.e. bear the contract responsibility to sell in the future), they are short positions or short on the futures

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

The service charge of okex bitcoin exchange is the lowest in the world, ranging from 0.15% to 0.02%, and there is no charge for platform currency okb

in bybit, for each successful order, bybit platform will automatically decide to charge or provide rewards according to the order attributes. For "market makers" in the market, the system will give 0.025% reward based on the contract value for each successful price limit order

for the "price receiver" in the market, the system will charge 0.075% of the contract value based on the contract value for each successful market order. A $5 bitcoin transaction may have the same handling charge as a $5000 bitcoin transaction

they are measured by satoshis

4. A mining Trojan named wanna miner uses & quot; Eternal Blue & quot; Loopholes spread in the local area network, the infected machine will be built into a robust Botnet, support intranet self-renewal, long-term latent in the computer to dig Monroe money.. Tencent security Royal see Threat Intelligence Center reminds enterprise users to be vigilant, and can choose Tencent computer manager security & quot; Imperial point & quot; Defense against such attacks.

5. If there is a mine, it will be safer, electricity will be cheaper and the risk will be less.

6. 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.

7. Fire coin network supports up to 4 times leverage.

8. Bitcoin was about $3800 a year ago, and now it's between $38000 and $41000.

9. In the case of bitcoin option, that is to say, you can only get the right after the goal is achieved. In the case of delivery contract, it is different. The delivery contract means that the value has been determined.

10. In 2010, a programmer used 10000 bitcoins to buy a pizza, which is the biggest single transaction I know. Maybe it sounds funny to me now, but at that time, bitcoin was only played by game players and programmers. There was no formed trading platform. The trading volume was small and the price was extremely low

this is also the first transaction between bitcoin and physical object I know.
