Already explained why I sent the money. (Because I dealt with the guy before with big amounts many times)

This just makes the Internet strangers less trustworthy than they already are, it's a sad thing that people are still doing this kind of stuff where they try to make you let your guard down and then suddenly pull down from under the rug the trust that you've given to them, it's such a sad thing that this is happening, hopefully OP finds the will to pursue legal action or do an investigation regarding this matter, I'm sure that it's not a bad idea to do it, at the least keep this scammer on his toes, make this person pay his sins with paranoia and anxiety, I'm sure that he will love that kind of thing and that's the best that you can do in this situation until he gives up and brings you back the money.

It’s not new in Bitcointalk or any anonymous forum that a reputable member turn into scammer when they are not getting anymore profit with their deals here.

Even VIP member or Legendary with high trust due to multiple successful trade like @yogg turn into scammer after his spendings on gambling is too huge compared to the product profit he is gaining here.

The scammer here is low rank with few positive trust. I’m sure it’s easy for him to ruin his account reputation for money.

I was his good customer and he lost me and his business. Well, lets move on and close the page.
