I've been thinking about a question: those so-called teachers who earn forever have indeed earned forever. Even if they have a capital of 100,000, earning a small target is just a matter of time, so why do they want to take you along?
First, for traffic, those who want to learn will open courses in the future (considered to have a conscience).
Second, photo editing, stealing images, editing chat records, and fake market simulations (to trick some membership fees, which is a bit clever for a poor person).
Third, to pull you to other exchanges for transaction fees (standard practice, if they have strength, there's nothing to say, but if they don't, it's a bit of a scam).
Fourth, taking others' strategies to make money (a bit clever, but easy to fail to notify in time, which can lead to losses).
Fifth, pure scams, notifying both sides, one more and one empty, whichever is right, they make that the chat record.
Sixth, pulling you to worthless platforms to incur losses (the most unethical, like being born without an anus).
