Recently, I figured out something.

The logic of some top-tier exchanges is actually very simple: small profits can be freely withdrawn to let you taste success; if you incur losses, you can borrow money to keep playing. But the key point is—absolutely no allowing you to make a large profit in a single transaction and then leave immediately. As soon as you try to withdraw a large amount of gains at once, you'll encounter various restrictions.

This is the core rule of casino operation. The higher user stickiness, the more stable the platform's revenue. They don't want you to make money and leave happily; they want you to stay in the platform ecosystem forever.

To put it plainly, most active users cannot truly achieve financial freedom and leave; they can only continue to be trapped within the system. This is the profit model of some top-tier platforms.
