The difference between 3000u principal and 100u-500u is significant. Let's calculate using mathematics. With 3000u, opening a minimum Ant warehouse with a 1 ETH hundred-fold leverage contract, the liquidation price is 2980 points away from the 3000u principal. If it’s 100u, then the liquidation price is over 90 points away from the principal. For a two ETH position, 3000u principal is over 1400 points away from the liquidation number, while 100u is over 50 points away. Therefore, 3000u is the most standard principal in the secondary market. #交易类型入门
