The main force wants to change hands, which means that the main force does not want too many startled birds who do not watch the market. What they hope for is more allies who can understand the intentions of the main force and follow them in trading. That way, the main force will have a much easier time.

If there are too many startled birds, then various methods will be used to make them leave, whether it’s making a profit or incurring a loss, it doesn’t matter. In short, the small retail investors' chips must keep changing hands; you cannot bring a group of startled birds from the bottom to the top.

It is true that the main force forces you to hand over your chips. But it's not handing them back to the main force; it's handing them to the next retail investor.

The last sentence: Study hard and make progress every day.

Otherwise, when you reach the peak and the main force hasn't left, if all of you profit at once and run away, the main force will be stuck at the top. Wouldn't the financial backer want to eliminate this main force?

When the main force is accumulating chips, you won't even pay attention to that pattern. You enter halfway up the mountain, and the main force hopes you make a little money or lose a little money, passing the chips to the next person, and this cycle continues to the peak.
