Guys thank you for your answers, and the time you lost for writing these messages. While giving you the question I lost 3$ and won nothing.
I thought that I will win, but the winner was another fake account of the owner of that scam.
Still, I believe that there are really good giveaway sites. But it should b hard to get to them
