Fortunately, if you do a very bad investment, you can sell all your assets, go bankrupt, and keep your life. Too bad the poor guy chose to take his life. But this again looks like not doing enough homework.
This is very sad. I wish these things were written in large red letters on the signup page for a trading account, and one would have to type them in first person, like "I realize that I can lose all my possessions as a result of a bad trade" (no copy-paste allowed) to even accept the terms of service.
