Is bitcoin margin deducted from profits

1. Trade website always wants to collect some profit, he frame server recruits employee to want money. Foreign websites see a small difference, because it is calculated in foreign exchange, the RMB price will be higher. It is also possible that the cost of these servers in China is a little higher than that outside.

Transaction mode of bitcoin

bitcoin is e-cash similar to e-mail, and both parties need "bitcoin wallet" similar to e-mail and "bitcoin address" similar to e-mail address. Just like sending and receiving e-mail, the remitter pays bitcoin directly to the other party through a computer or smart phone according to the recipient's address. The following table lists some websites that download bitcoin wallets and addresses for free

a bitcoin address is a string of about 33 characters long, consisting of letters and numbers, always starting with 1 or 3, such as & quot& quot; Bitcoin software can generate address automatically, and it doesn't need to exchange information online, so it can be offline. More than 2 bitcoin addresses are available. Figuratively speaking, there are about two grains of sand in the world. If there is an earth in each grain of sand, then the total number of bitcoin addresses far exceeds the number of all the sand on all these "earths"

the bitcoin address and private key appear in pairs, and their relationship is just like the bank card number and password. A bitcoin address is like a bank card number, which records how much bitcoin you have on it. You can generate bitcoin address at will to store bitcoin. When each bitcoin address is generated, a corresponding private key of the address will be generated. This private key proves that you have ownership of the bitcoin at that address. We can simply understand the bitcoin address as the bank card number, and the private key of the address as the password of the corresponding bank card number. Only when you know the bank password can you use the money on the bank card number. Therefore, please keep your address and private key when using bitcoin wallet

after the transaction data of bitcoin is packaged into a "data block" or "block", the transaction is initially confirmed. When a block is linked to a previous block, the transaction is further confirmed. After six block confirmations in a row, the transaction was irreversibly confirmed. Bitcoin P2P stores all transaction history in a "blockchain.". The blockchain continues to extend, and once new blocks are added to the blockchain, they will not be removed. Blockchain is actually a distributed database composed of a group of scattered client nodes and all participants, which is a record of all bitcoin transaction history. Nakamoto predicts that when the amount of data increases, users hope that not all the data will be stored in their own nodes. In order to achieve this goal, he uses the hash function mechanism. In this way, the client will be able to automatically eliminate those parts that it will never use, such as some very early bitcoin transactions

4. Bitcoin transaction refers to the transfer between an address and another address, which usually requires an additional service charge to miners

generally, an ordinary bitcoin transaction is composed of one input and two outputs, with the size of about 200 bytes. The default charge is 0.0001btc for every 1000 bytes, and the ordinary bitcoin transfer fee is about 0.001-0.002btc

however, e to the limited capacity of the block to hold transaction records, miners generally give priority to the transaction with higher handling charges. Therefore, when the transaction needs urgent confirmation, it is recommended to select custom charges. I also saw these in Yingfu College of Finance and economics.

5. It is often said that you can send bitcoin to any corner of the earth for free. Generally, you can transfer bitcoin for free, but in some cases, you have to pay transaction fees to complete the transfer. In version 0.8.3 bitcoin wallet, the default is 0.0001 bitcoin transfer fees. This service charge is awarded to miners to encourage them to continue mining and provide enough computing power for bitcoin to ensure the security of bitcoin network. At present, the main income of miners is to get 25btc reward by creating new blocks, but this reward is halved every four years. As time goes on, bitcoin transaction fee reward will graally replace the reward for creating new blocks. Under what circumstances do you need to pay the handling charge? How much does bitcoin charge? What is the handling charge? Bitcoin system has a series of network rules, including fee 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 stored in your wallet until you spend it. If you receive two payments from 3btc and 2btc, their records in the wallet are independent of each other, that is, a 3btc and a 2btc, rather than merging them into 5btc (the wallet only records transaction details and does not merge the balance, but you can see the total balance on the interface of the wallet). As time goes on, many bitcoins of different amounts will accumulate in your wallet, So when you send bitcoin, the wallet has to decide which bitcoin is the 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. If your outputs are less than 0.01btc (including the fund changes inside your wallet), you have to pay a handling charge of 0.0001, even if you transfer it to yourself. The wallet has an established rule when preparing your payment amount, 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 pay 5.005btc, 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, and 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. If you do have a large amount of small input and want to transfer it out for free, you can add a large amount of bitcoin with a large age, which will increase the average priority, so that you can transfer out bitcoin for free
4. Charge per kilobyte. At the end of the transfer, the client will detect the size of the transfer (in bytes). The size 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, there will be a handling charge. The cost of 1000 bytes is 0.0001btc by default, but you can also add it in the client. Open 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.

6. Bitcoin trading is the business of bitcoin. Of course, you can make money by buying and selling bitcoin, but you should pay attention to that you may lose money

ten million investment roads, safety first, nonstandard operation, two lines of tears for relatives! The simplest is to hold bitcoin, and the most extreme is to leverage it all
the compromise is that in addition to holding BTC, we should also invest in some counterfeit currencies and use futures to do band. We should be conservative and only short, not long, but also lose money. If the owner of the building has a tendency to invest, it is suggested that you go first and learn about it.

7. Use the lilac browser. A behavior value contribution reward mining browser, lock more, dividend more, return more. Register your account and log in. Open the mining settings and you can mine. Usually browsing the web and no money, open this, every day can dig dividends, registered users login on the line.

8. All right

9. Whether the security deposit of bitcoin can be dected from the account mainly depends on the agreement at that time

10. It is suggested that you do not transfer margin. You should know that there is no formal virtual digital currency trading platform in China. For your capital security, please choose the investment mode carefully.
