The Binance event contract has become increasingly disgusting after the upgrade. This morning, I saw that the fee rates changed from 80% to 75%. This means that if the order amount is the same each time, the profit and loss ratio points increased from 55% to 57.1%. The most disgusting part is that shortly after, it changed again to 74%, and the break-even point rose to 57.4%. Previously, the order amount for BTC was reduced from 250 to 125. The step-by-step operation is really disgusting. It is said that Binance can dynamically modify the rates through its own backend data to keep itself in a state of perpetual profit (or even making more). Really, if they don't want to let us play, they should just shut it down. Don't do such disgusting things! I have been continuously optimizing my trading strategy for the past few weeks, just raising my profit and loss ratio points to between 55% and 56%, and then they raised it. I even suspect that this profit and loss ratio point may change dynamically for different people (accounts). They keep lowering the rate (increasing your break-even point) as you earn more. It's really disgusting...
