Selling U went wrong, I was supposed to transfer 34,000, but I saw it as 246,160 in RMB and transferred 246,160 U.

I over-transferred by 21 WU, about 1.5 million RMB, and then the other party transferred it back to me.

The other party is wealthy, a little less than 100 million, running a company in the real economy.

This is the comfort of dealing with wealthy people: the poor devise schemes, the rich cultivate integrity.

Wealthy people may not genuinely have integrity, they just don't want to get into trouble over a mere million or so, which involves a kind of game theory.

There have been others who transferred incorrectly to me; I remember one time it was about 5 WU and another time 10 WU. In the case of 10 WU, the other party was also a Chinese American in the U.S., and I returned it to them as well.

Because my reputation is very valuable, I would not tarnish it for this small amount of money.

Similarly, which exchange is the safest?

This field lacks regulation; whether to do evil depends entirely on one's conscience. The reality is that the wealthiest have the integrity, and those who are the largest also possess integrity.

The wealthiest face the highest costs for wrongdoing, and the losses from wrongdoing are greater, so the ongoing trend will choose not to do evil.

Many small exchanges offer 80% or even 90% commission rebates, but while you seek cheap transaction fees, they are eyeing your principal.

Under game theory, I will only choose the wealthiest and also the safest, Binance. 😋😋😋
