The CoinBene Crypto perpetual contract is a digital currency contract priced in USD and settled by crypto. Each contract has a face value of 10 USD and supports long and short two-way positions. Perpetual contracts will not be settled, and the capital cost mechanism is used to keep up with the spot market price to the greatest extent. Use reasonable mark prices to calculate unrealized profit and loss and liquidation prices to avoid frequent unnecessary liquidation caused by market fluctuations. Perpetual contracts support a maximum leverage of 100 times. The goal of this contract is to allow high leverage to replicate the market conditions in the spot market.
Take the BTC-SWAP contract as an example:

Traders who want to profit from the current rise in the Crypto index will buy long this contract. On the contrary, traders who believe that its value will fall will sell the contract short.
Examples of transactions:
· A trader goes long 100 BTC of BTC at a price of 5,000 USD. He is long 100 BTC * 5,000 USD = 500,000 contracts. A few days later, the price of the contract increases to 6,000 USD.
· Profit will be: 500,000 * 1 * (1/5,000 - 1/6,000) = 16.67 BTC
· If the price had in fact dropped to 4,000 USD, the trader's loss would have been: 500,000*1* (1/5,000-1/4,000) =-25 BTC. The loss is greater because of the inverse and non-linear nature of the contract.
· Conversely, if the trader was short then the trader's profit would be greater if the price moved down than the loss if it moved up.
