Record some thoughts, no matter when there will be people making money and losing money. I have never been a market maker, so I don't know what the psychology is like. I feel that short squeezes and forced liquidations are the times when they make the most money. For example, if Ethereum gradually rises, the market maker's cost might be very high. A rapid surge over three months can already cover the losses from the short sellers who have been liquidated, not to mention the sell-offs above.
