Many old users hear 'rebate' and say: Oh, I've used my account for a long time, I can't open it.
I just want to ask: Is there anyone who transfers money to you regularly?
If not, then it's not bound, and you can still get rebates!
This is not a complicated process; just bind it, and it will be permanently automated.
If you are willing to give money to the platform, I won't stop you,
but knowing that this money can actually come back and not taking action is really hard to explain.
