If you understand, you won't lose,

I think I've understood the tactics of these trading personnel.
At the same time, opening dozens of accounts, with a capital of 1000, leveraging to the maximum, hedging both long and short positions, whichever account has the highest profit, that’s the one they promote. The account with the highest profit is used for attracting followers, and each time only 1% to 2% of the position is opened, which is stable.
Then they promote the other accounts, getting you to follow their trades, just to take a 10% cut of the profits.
Even if they incur losses, it doesn’t matter; they’ve already made plenty from the cuts.
Don’t easily trust these quantitative trading personnel!
