It's actually a crazy world. For civility sakes, let's say it's sheer carelessness that makes people do something as irrational as what happened. Otherwise, I would just put it as stupidity too. It's sad that people still get to lose their funds this way when they can easily get burner wallets to try these things out. It doesn't cost much time to create one. Just a few minutes.

Having loads of money doesn't bestow wisdom on people. Being wealthy doesn't also mean one is that smart. They could stumble on wealth through inheritance too. Does that also make them smart and rich? Of course, not.
