I totally agree with you and I had a rather funny experience when I was neer London at a crypto conference with some Chinese guys which told me to join their program and I could get a BMW and some other great things. On top of that their line to encourage me to invest was something like this: "Do you want to fly like an eagle my friend..?"

Of course I've figured out it was a scam but I stays at their presentation just to see how far they can go. I left afterwards and simply couldn't stop laughing of the experience with them, but some other people might believe them.
