Well, when it comes to money. We really can't avoid this kind of stuff. Scammers, Hackers, Fraudster and so on. Specially in cryptocurrency wherein we're in our personal information is hidden. We're anonymous. So getting tricked is so easy. Doing this kind of bad things is easy because no one knows our information. So i really do suggest just be more careful when it comes to your private keys. Make sure that it is hidden where no one can access it and also dont trust anyone unless you really pretty know that person your speaking with.
