Service charge BTC permanent in and out of the warehouse to do
if you sell 10eth with 1btc, 0.2% eth Commission will be dected, and 9.98eth will be obtained from the sale
if you buy 1btc with 10eth, you will get 0.998btc by decting 0.2% BTC handling charge.
first of all, we should understand that this service charge is given to miners to encourage them to continue mining and provide enough computing power for bitcoin, so as to ensure the security of bitcoin network. At present, the main income of miners is to get BTC reward by creating new blocks, but the reward is halved every four years. As time goes on, bitcoin transaction fee will graally replace bitcoin reward
under what circumstances should the handling charge be paid? What's the amount
bitcoin system has a series of network rules, including the handling charge rules, which are "what the client should do". When you use bitcoin client (wallet, bitcoin QT) to send bitcoin, the whole process is roughly divided into the following steps:
1. Prepare the bitcoin you want to send
the client is responsible for collecting the balance of bitcoin in your wallet (bitcoin QT) to prepare for payment, Because every bitcoin you receive is in your wallet until you spend it
if you withdraw 3btc and 2btc twice in okcoin bitcoin, their records in your wallet are independent, that is, a 3btc and a 2btc, instead of merging them into 5btc (the wallet only records transaction details, but does not merge the balance, but you can see the total balance on the interface of the wallet), As time goes on, you will accumulate a lot of bitcoin in your wallet. It is conceivable that there should be thousands of such records in okcoin bitcoin wallet. So when you send bitcoin, the wallet must decide which of the above records are most suitable for this sending
the bitcoin you get in a transaction is called "inputs" and the bitcoin you spend is called "outputs". There are multiple inputs and outputs in your wallet
2. Prevent a large number of micro payments from impacting the network
if you recharge the okcoin bitcoin trading platform less than 0.01btc (including the fund changes inside your wallet), you must pay a handling charge of 0.0001. When preparing your payment amount, the wallet has an established rule, that is, when preparing the payment amount in many inputs, try to avoid the amount change less than 0.01btc (for example, if you want to recharge 5.005btc to okcoin bitcoin, the wallet should choose 3 + 2.005 or 1 + 1 + 3.005 instead of 5 + 0.005)
3. The larger the amount, the higher the age of the currency, the higher the priority
if the amount you send is too small or your bitcoin has just been mined, then your transfer is no longer free. Each transaction will be assigned a priority, which is determined by the degree of currency, the number of bytes and the number of transactions. Specifically, for each input, the client will first multiply the number of bitcoins by the time they exist in the block (currency age, age), and then divide all the procts by the size of the transaction (in bytes). The calculation formula is: priority = sum (input)_ value_ in_ base_ units * input_ age)/size_ in_ If the calculation result is less than 0.576, then the transaction must pay the handling fee. This is why you need to add a 0.0001 when you withdraw with okcoin bitcoin, because the bitcoin transfer in okcoin wallet is frequent, and the time of bitcoin in the block is relatively short, so you need to pay a handling charge. If you do have a large number of small inputs, such as small miners, and want to transfer them out for free, you can add a large amount of bitcoin with a large currency age, and the average priority will be increased, so that bitcoin can be transferred out for free
4. Charge per kilobyte
at the end of the transfer, the client calculates the size of the transfer (in bytes), which generally depends on the amount of input and output. The calculation formula is as follows: 148 × Input amount + 34 × Output amount + 10. If the size of the transfer exceeds 10000 bytes, but the priority meets the free standard, you can still enjoy the free transfer, otherwise you need to pay the handling charge. The cost per 1000 bytes is 0.0001btc by default, but you can also add it in the client by opening the tab "settings & gt; Options & gt; The main purpose is to adjust the handling charge. If the service charge you are setting is less than 0.0001, BTC is calculated as 0.0001. When this rule applies, it will replace the rule in step 2 instead of accumulating.
there are two ways to trade bitcoin, one is spot trading, also known as currency trading, which requires the purchase of usdt (omnilayer protocol based digital assets released on bitcoin blockchain), and then the purchase of spot, and the other is futures trading. the futures trading is divided into delivery contract trading, which is generally a weekly contract, Next week contracts, quarterly contracts and perpetual contracts
6, when I successfully transfer my bitcoin recharge to the trading platform, I can sell my bitcoin on the trading platform. On the trading platform, click the "sell bitcoin" option under the trading column
7. Then select the type of order to sell, the quantity of bitcoin to sell, and click the "next order" button to continue
Similarly, the record of selling bitcoin can also be seen in the transaction query under the transaction column9, when the transaction is successful, you can withdraw RMB to your bank card. Under account management on the left side of the page, click "RMB withdrawal", and then fill in according to the required format in the right pane. Finally, click the "withdraw" button
but you have to charge for closing yesterday's position and opening again
The bilateral service charge of futures means that a complete transaction consists of opening and closing positions. When opening positions, the service charge will be collected once, and when closing positions, the service charge will be collected again. This is called bilateral service charge, which means both opening and closing positions should be collected
for example:
Shanghai Stock Exchange Futures Commission: (yuan / hand)
copper: contract value 0.0002
aluminum: 5 yuan / hand
zinc: 8 yuan / hand
Rubber: contract value 0.0002
Gold: 30 yuan / hand
fuel oil: 2 yuan / hand
coke: 8 yuan / hand

< H2 > extended dataactual profit and loss
the profit and loss realized by position closing is called profit and loss Actual profit and loss. The vast majority of futures contracts are closed by closing positions
the calculation method of Long's actual profit and loss is: profit / loss = (closing price - buying price) x position x contract unit - handling charge
the calculation method of short's profit and loss is: profit / loss = (selling price - closing share) x waiting quantity x contract unit - handling charge
when there is risk in the futures market, some members have insufficient trading margin or overdraft e to excessive trading loss. The proceres of the settlement system to deal with risks are as follows:
1
(2) if the margin supplement is not in place, first stop the member's opening new positions, and compulsorily close out the member's open position contract:③ if the member's margin balance is not enough to make up for the loss after all positions are closed out, use the member's settlement reserve in the exchange
(4) if it is still insufficient to make up for the loss, the membership fee and seat fee of the member shall be transferred (5) if it is still insufficient to make up for the loss, the risk reserve of the exchange shall be used and the member shall be pursued at the same timesuppose that you have a BTC with a value of RMB 100000 to trade in a contract, with 50 times leverage and a position value of RMB 5 million (100000 * 50 times). Suppose that you are a taker in the process, you need to pay 3000 yuan (5 million * 0.06%), and if you are a maker in the process, you need to pay 1500 yuan, accounting for 4% and 2% respectively.
