It seems that he is not a serious trader. Watch out for yourselves. I was not scammed because he was supposed to go first. He was supposed to gift me a cheap game of my wishlist (0.69€) for battlerite lite. He never delivered but that's not the problem as you can always change your mind before nothing is exchanged. It is worse as he made up some stories about how he could not buy it on steam himself and will have someone else gift it to me. He even made me add a person for that. A person who had no idea of what was happening. I don't even understand why he went through all this shit as he was supposed to deliver first. He just should have stopped the trade!
Here are 3 screens (and i even have a mail from the supposed store he used affirmeing that they never had anyone asking them for such a thing).
First me asking the person:

Me confronting him and him writing, maybe to come up with another lie:

Me giving him a last chance...

Then i blocked him and deleted him from my friend list.
