Since I play a role in this, I will pay you back in the near future, as soon as I pay my debts on the forum. although I have nothing to do with it. I only use 1-2 addresses on this forum.
The situation is terrible, and I was completely surprised to read a message from you in the form of " Send me my $ 90"
It would be stupid to go to your tsele, as well as to DT2 and be active on the forum, which would spoil everything because of 0.009 btc
/// but this is alarming.. I don't see any transactions for this address today..
For as long that you didn't received BTC on your wallet address that you provide via PM then you don't have responsibility to pay it back to him since this is an obvious scam attempt. The OP must be cautious when trading especially when the transaction happened outside the forum.
Don't be afraid on losing DT2 title for this scenario because if you give up then they will keep doing this kind of scheme to other DT.
