Unsurprisingly, it is easy to lose your spouse, children, etc. if you're at the point where you've already lost all your money. Because very likely, you've also lost their money in the process. I've seen people lose their family and friends, too.
People take out mortgages, credit card loans, loan money from friends, family, colleagues. Are intentionally opaque about their financial situation.
Then if things go bust, and people want their money back, they're stuck alone with the mess.
At its core, it's due to breach of trust.
