We know that Bitcoin is a distributed virtual currency. Its entire network is composed of users. Unlike a central bank, it is not issued by a central agency. The decentralized feature of Bitcoin can be said to be safe. With the guarantee of freedom, everyone can mine, buy, sell or receive Bitcoin regardless of location. However, if you want to control Bitcoin, you need a private key. The private key is isolated and stored in any storage medium, and no one can obtain it except the user himself. Many investors who want to invest in Bitcoin still don’t know how to buy Bitcoin? Let the editor of the currency circle introduce to you the Bitcoin trading tutorial.

Bitcoin trading rules

1. Transaction type

Transaction types are divided into two categories, opening and closing positions. Opening and closing positions are divided into two directions: buying and selling.

Buying to open a long position means that when a user is bullish on the index, he or she will buy a certain number of new contracts. Carry out the "buy and open long" operation, and the long position will be increased after successful matching.

Selling long refers to the selling contract that the user covers when he is no longer bullish on the future index market, and offsets the current holding of the buying contract to offset the exit from the market. Perform the "sell to close long" operation, and the long position will be reduced after successful matching.

Short selling means that when a user is bearish or bearish on the index, he or she will newly sell a certain number of certain contracts. Carry out the "sell and open short" operation, and the short position will be increased after the matching is successful.

Buying short refers to buying contracts that users cover when they are no longer bearish on the future index market, and offset the current selling contracts to offset the exit from the market.

Carry out the "buy and close short" operation, and the short position will be reduced after the matching is successful.

2. How to place an order

Limit order: Users need to specify the price and quantity of the order. Limit orders can be used for both opening and closing positions.

Place an order at the counterparty price: If the user chooses to place an order at the counterparty price, the user can only enter the order quantity and cannot enter the order price.

The moment the system receives this order, it will read the latest opponent price and place a limit order at this opponent price.

3. Position

After the user opens a position and completes the transaction, he or she will own the position, and the positions in the same direction of the same contract will be merged. In a contract account, there can only be a maximum of 6 positions, namely long position on the current week's contract, short position on the current week's contract, long position on the next week's contract, short position on the next week's contract, long position on the quarterly contract, and short position on the quarterly contract.

4. Order restrictions

The platform will limit the number of positions held by a single user for a certain period of contract and the number of orders placed for a single opening/closing position to prevent users from manipulating the market.

Through the above Bitcoin trading tutorial, I believe everyone can quickly learn how to buy Bitcoin. As the earliest and largest cryptocurrency to date, Bitcoin was born at the same time as the blockchain. Because the total amount of Bitcoin is capped at 21 million, its rarity can guarantee its value. Logically speaking, the settings of Bitcoin are actually the same as those of gold. The issuance limit of Bitcoin cannot be exceeded just like gold. Gold is not issued by any country, and the same is true for Bitcoin. In fact, Bitcoin can now be circulated like currency, which is the embodiment of the value of Bitcoin.
