Thanks everyone for understanding and supporting my flag.
Yes, I was really naive and didn't take the safety precautions that were due. The fact that I'm a newbie here also doesn't helped on tracking and checking the scammer profile.
Yes, it's true that can't absolutely prove that this user scammed me, probably it wasn't the first time he made it (and won't be the last) as he has a clear strategy so he deletes every evidence of the scam when discovered.
Also, I'm a started, it would be my first miner and that enthusiasm led me to lower security mesures before making the deal.
I'm a long time user of many forums, my username can be searched and found in many many sites, "Gyzdark" it's always myself, from pornhub, to bitcointalk, to LoL, to Steam.... everywhere. I have an 13-to-0 good feedback on a Portuguese technology forum (ZWAME) for buys and sales and a couple more in other technology forum. I exist, I am and I will be here, always the same person. Who is this "ParleFrenc" user? He is a nobody, he wont even tell me where he will ship the good from, just said "Europe, dont worry". He will say "Isn't anonymity the whole purpose of bitcoin, why are you asking for information, to track me down?" has he said in our chat. But, no, anonymity isn't the whole purpose, the purpose is a decentralized, self regulated market, anonymity is just one of the good features that comes with it all. Unfortunately it is also a birthplace for scammers and faceless slugs whiling to sell his own mother for a couple dollars like @ParleFrenc is, that has to live with his face under the dirt because he is just too horrendous human being to be himself on the internet.

Thanks everyone on this forum, keep up the good work. Fortunately was the 2nd time I got scammed (1st one I bought a GPU, it was malfunctioning and managed to repair it) it was another lesson for me.
It's nice to know you have a detection system for multi-acount scammers like this one, will pay more attention in the future.
Thank you and sorry for bother.
I'll stay here, on this forum for a while whiling to learns and also help when I can so, we'll see ourselves!
