If you recently find that a friend has suddenly become irritable and short-tempered, even turning hostile towards you, even though you haven't done anything to wrong them and have treated them the same way before, it's safe to say they're about to lose everything. And as the market gets colder, this will likely become more frequent. I experienced the same thing a few years ago when I was almost penniless.

My friend is different. He attacks whether he's winning or losing; his main strategy is offense.

Offense is the best defense

The main principle is to attack the unhappy.
