Please be wary of some "Shen Dun" (shield) big sellers using lead-generation to lure people into pig-slaughter scams. Specifically which ones, I won’t say.
The transaction verification will look at your trading records and profit rate, then assess your payment capability to judge your level of competence. They’ll lead you into getting guided trading with onboarding or some backwater “junk” platforms, and then carry out pig-slaughter scams.
So, the verification requirements include all kinds of screenshots and back-and-forth talk that gets you to comply. Basically, it’s all just selling on the surface; in reality, they infiltrate to identify and target potential victims.
