There are many related articles online, and they are all quite good. For most people, the most important thing is how to be the safest #出u .
It's actually very simple. You just need to ensure that the funds you receive are clean, and that is the safest.
So what funds are the cleanest and safest?
I think the borrowed funds taken from the bank are the cleanest, so as long as you only accept borrowed funds, you can ensure that the funds you receive are clean.
If you cannot confirm whether the funds are borrowed, you can request to verify the transaction records to determine.
One thing to note is: do not exchange cash offline!!!
This is crossing the line. Once the other party has a problem, you are not safe.
