There's not much market activity, so let me share some thoughts that are worth considering.

I also watched and then thought about it. With thinking, there is room for improvement. Once improved, the probability of making money will increase.
We cannot passively make money; the second-hand market must have the ability and mindset to actively generate profits. The same goes for trading; one must be proactive in identifying entry signals and controlling risks, so that one can survive longer.
