I don't know how many people have been deceived by the term "trading system" that many ups have talked about, saying things like take profit and stop loss. Today, I will tell you what a real trading system is, which consists of three major points: 1: Having a Spot grid that can steadily earn you u every day. 2: Holding BTC Spot or other valuable coins in Spot. 3: Keeping about 20% of your USDT. The following is trading. Simply put, the premise of the big plan is to consider the small plan. The three points above seem simple, but the operation is like this: you have a Spot grid of several thousand u that can bring you about 200-300 u of profit each month. Also, having Spot means you won't be afraid of missing out when the market rises, which creates a psychological effect. Moreover, the u earned from the grid can be used to buy those high-value coins in Spot in a cycle. That 20% of u is for facing a big dump one day, for example, if BTC suddenly drops by around 20%, you can buy in and wait to earn.
