Just see things realistically. How much is 13 ETH worth? Why do these kinds of giveaways? I'm probably a big skeptic, but I don't believe in such "gifts". And the one who believes in such "gifts" must grow up either on someone else's experience and if he does not believe in other people's mistakes, then he will have to learn from his mistakes.
Once again, never believe in these kinds of giveaways.
Just look at the date the site was created.
