Is it my imagination or that in front on his trading setup is a box of disposable paper tissues?

A bottle of hand sanitizer (lube?) and a mini fan?
What kind of trading was this guy actually doing? I would not be surprised if that is the same set up he used to play on several poker tables at the same time when no one was watching, Jesus Christ.
I think you might actually be right...

In any case, I would say it's the people's responsibility to remove their money from an exchange. If you keep your money in control of some random person, that random person will do whatever they want with it.
