That's how it looks like when people learn about thread safety and atomicity for the first time in their life - AFTER coding an exchange platform.

Just try it out, there is an API after all...
Also for the record,
Tomorrow, Tuesday,
will make 1-week from
Wednesday last week the 29th
since I made my withdrawal request.
You guys need to really take a look at
that new withdrawal policy you have implemented,
Don't see how anyone could think that is good business practice,
You are only going to lose customers behind having a police like this in place.
Seriously !
Today, Monday, is the second business day since your withdrawal request (Friday was a national holiday in HK).
Monday is also a public holiday in HK ...
