It is all REAL BTC.
Okay. Where is it on the blockchain? txid please.
TradeFortress offered you all a 1 BTC IOU, he said he owed you 1 BTC each. He essentially wrote you a cheque for 1 BTC with an empty bank account. The trust lines he asked you to set, was asking you to extend 100 BTC credit to him, which he could incur in debt.
An IOU in the absence of any consideration is just a naked promise. Completely unenforceable.
TradeFortress pays me my 10.15 BTC back, or he is 10000% scamming, deceiving, and foolish.
What 10.15 BTC? What are you talking about, back? Show me the txid where you transferred 10.15 BTC to him. A blockchain url will suffice.
