Recently, I’ve noticed a surge of new faces in the crypto world. They often show off luxury watches and designer brands on social media—like LV super A replicas, Rolex Submariners... At first, I was quite envious, until a "big brother" approached me.

He first praised my potential, then tried to sell me a @399@ "Cognitive Enhancement Course," claiming he could guide me step-by-step to make big money in blockchain. Sounds good, right? I casually looked at his Moments.

Details determine everything—I stared at his Rolex on his wrist for a long time, and suddenly realized: the tiny crown on the gold-plated Rolex is actually round. It should be a six-pointed star, just like a real Rolex.

Just this one detail, and the entire "big brother persona" collapsed. Later, I understood that this routine is too common in the crypto circle: package a persona → build trust → harvest tuition fees. Instead of buying courses, it’s better to learn how to read people.
