Many new friends who are just entering the crypto contract world often hear others say 'liquidation', 'doubling', 'ten times leverage', 'going long or short', and feel confused. Today, I will explain in the simplest way how to make money with crypto contracts.
1. What is contract trading?
Contract trading is essentially betting on direction: if you judge that the future coin price will rise, you 'go long'; if you judge it will fall, you 'go short'.
Moreover, crypto contracts usually come with leverage, meaning if you have 100U, you can operate as if you have 1000U (10x leverage), so a 1% increase means you make 10%, and conversely, losses occur more quickly.
