Liquidation: More severe than 'losing all the principal' - 'forced liquidation' 🔥🔥🔥

Assuming you have 10,000 yuan in margin and have leveraged 5 times to buy bit (equivalent to borrowing 40,000 from the platform, totaling a position of 50,000 yuan). If bit suddenly drops 25% that day, your 50,000 yuan position directly loses 12,500 yuan - at this point, you only have 10,000 yuan in margin, which cannot cover the 12,500 yuan loss, and the platform will immediately force a liquidation. In the end, you not only lose the 10,000 yuan principal but may also have to make up a small difference (in rare cases).

Position: A colloquial term for 'holding without selling' 🔥🔥🔥

Last week you spent 3,000 yuan to buy 10 of a certain altcoin, planning to sell when it rises to 4,000 yuan, and for the past few days the coin has been sitting in your account, which is called 'holding position';
Last year you bought 0.5 bit, planning to hold it for 3 years and see, this kind of 'long-term holding' operation is called 'long position';
You bought eth in the morning, planning to sell when it rises a bit in the afternoon, this kind of 'short-term holding' is called 'short position.'

Eating orders: an operation of 'actively matching to complete a transaction' 🔥🔥🔥

You're eager to buy 1 eth, you open the trading interface and see someone has posted a sell order for '1 eth at 1800 dollars' (this is called a 'sell order on the board'). You don't want to wait for a lower price, you directly clicked 'buy,' and instantly matched with this sell order — this is you 'eating the other party's sell order.' Conversely, if you're eager to sell Ethereum, you directly click 'sell,' and match with someone else's buy order for '1 at 1790 dollars,' that's 'eating the other party's buy order.'
Trading coins: it's not 'playing around,' it's high-risk 'buy low sell high / sell high buy low.'

Going long: you judge that bit will rise, buying 1 at 20,000 dollars, and selling when it rises to 25,000 dollars, netting a profit of 5,000 dollars;
Going short: you judge that eth will fall, first borrowing 1 from the platform (at that time the price was 2000 dollars) and selling it, then buying it back when it drops to 1500 dollars to return to the platform, netting a profit of 500 dollars.

Cancelling orders: 'cancelling uncompleted orders' 🔥🔥🔥

In the morning, you placed a sell order for 'eth at 1800 dollars,' planning to sell when the price reaches that point. However, at noon when checking the market, you see eth is rising towards 2000 dollars, you feel that selling at 1800 would be a loss, so you hurriedly clicked 'cancel order' in the 'order history' — this unfulfilled sell order has been cancelled, and you can place a new sell order at 2000 dollars.

Position: the amount of money you used to buy coins, and the proportion of that money relative to your total principal 🔥🔥🔥

For example, you have a total of 100,000 yuan in principal, and you used 30,000 to buy bit, which means '30% position'; if you bought all 100,000, that's 'full position'; if you only bought 10,000, that's 'light position.'
