Many people are unaware of a detail that causes both themselves and their friends to fall into traps — the issue of rebate binding.

Let's start with the current situation: a single ID card can usually only be bound once for rebate at a major exchange. Sounds fine? That's where the problem lies.

Some might think of cheating by unbinding and then binding a new account. But what happens? Neither party benefits —

After your friend cancels or unbinds, even if they re-register with the same ID, the system will recognize the identity as invalid. You still won't receive the commission, and they won't get the rebate. A wasted effort and a permanent loss of fee income. In plain terms, it's a double loss.

So, what is the correct approach?

First, only use IDs that have never been registered before. That's the foundation. Second, don't blindly pull in users; focus on attracting genuine new users. New users have the highest value and are more cost-effective. Most importantly, clearly communicate this rule so the other party understands. Only then can you build a professional trust relationship and establish long-term cooperation.

Honestly, information asymmetry exists, but don't exploit others' ignorance for a small short-term gain. Ruining someone else's long-term eligibility for a quick profit is harmful to both sides. Set clear rules before taking action — that’s responsible for both parties. That’s the smart way to do it.
