Authentication code of bitcoin

1. You can go to the domestic bitcoin trading platform to register an account. Now you need real name authentication. If you want to store bitcoin, there are many online wallets. You can register and store bitcoin in it. Of course, you can also download a bitcoin wallet client. If you know the technology, it is recommended that you do this, which will be safer. If you don't know the technology, you can register a wallet online.

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

3. I've also had this problem. The main thing is to write the correct wallet address in the address bar What I met is that the address bar can't be pasted), so I have to input it one by one manually. More than 30 letters, including case and number, should be 100% correct. I think it's the same thing.

1. By definition,

leverage trading is to use small amount of funds to invest several times of the original amount in order to obtain multiple returns or losses relative to the fluctuation of the investment object

A contract is an agreement in which the buyer agrees to receive an asset at a specific price after a specified period of time and the Seller agrees to deliver an asset at a specific price after a specified period of time

2. Operation method

leverage is to allocate assets in excess in the spot market through platform currency borrowing, and the operation process will include currency borrowing rate + transaction rate

contract is a delivery contract mode, which means that the leverage ratio of the proct itself can be selected before trading

3. Rules

leverage trading is that investors use their own funds as a 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

futures contract is a standardized contract designed by the exchange and approved by the national regulatory authorities

{rrrrrrr}

extended data

the international financing multiple or leverage ratio is between 20 times and 400 times, and the standard contract in the foreign exchange market is RMB 100000 per hand (referring to the base currency, which is the previous currency of the currency pair)

if the leverage ratio provided by the broker is 20 times, the margin of 5000 yuan (if the currency of the transaction is different from the gold coin of the account guarantee, it needs to be converted) is required for the transaction

the reason why banks or brokers dare to provide a larger proportion of financing is that the daily average fluctuation of the foreign exchange market is very small, only about 1%, and the foreign exchange market is continuous trading. With perfect technical means, banks or brokers can completely use less guarantee money from investors to resist market fluctuations without having to bear their own risks

Foreign exchange guarantee metal is used for spot trading and has some characteristics of futures trading, such as trading contract and financing, but its position can be held for a long time until it is voluntarily or compulsorily closed

5. Don't play leverage trading, bro. Speculate in Harbin futures t & # 10133; 0 is still OK
