You're stating the obvious here, and there's no point even discussing this.
Anything you own, whether it's gold, crypto, cash, or comic books, can get stolen if you don't have proper security measures in place. That's been known as long as there's been thievery in this world.
I don't even know how the OP got a shred of merit. It is nothing original tbh. He is just stating what is currently continuously happening, although I suggest for the OP to revise the topic and discuss the security of crypto in some other ways rather than those obvious password character limits and such.
