In the trading market, it is not meaningful to overly focus on the ethical issues of market makers. The key is still the value of the assets themselves and the long-term stability of the market. Market makers are just one part of providing liquidity, and what truly determines prices are supply and demand, as well as consensus. If a market maker violates regulations by smashing the market, such as selling without buying, leading to a price collapse, short-term fluctuations may actually be an opportunity to increase positions - provided that you believe the fundamentals, technical strength, and market demand of the project are solid.
