I ask my lawyer , he say :
How can they ask you, to contact an attorney, to affirmed that you did a transaction with an other man if he didn't see the transaction ? It's impossible.
But they know it of course.
And in my case, it's minus than 1 BTC.
They have all documents about me.
But no problem. They scam me. Ok. Now, maybe english is not my main language, but I'm now contacted by french specialist media in Cryptocurrencies & High tech to expose what they are doing with me and a lot of customers. Maybe after they will write a news about this, some english media will accept to talk about HitBTC scam.
Thank you again for your support here, I don't want to flood this forum.
Sorry for this.
