Smart contracts are not only powerful AI intelligence, but also very frightening tools for gathering wealth. Smart contracts have harmed many people! Although Bitcoin has made many millionaires, it has also plunged many into despair. It's like a gun; it can protect oneself, but it can also kill others. How much money you have in your account can be monitored by the backend of the door, first targeting those close to the liquidation price, then those further away. In extreme cases, the liquidation price with a long wick candle of 0 means pulling the plug and playing with data, abbreviated as "getting liquidated," and it will be as swift as lightning. In other words, if jys is born, we must die. If jus dies, we may not necessarily live. In the end, it is still the hundreds of millions of common people who suffer.
