I just read the whole conversation. COINMAN1 & brazilcoins were agreed to $$$ Unit, so COINMAN1 must pay the exact amount that brazilcoins sent him regardless of BTC unit. Delay of COINMAN1 caused the loss, if COINMAN1 completed the deal in time, there wouldn't be any problem.
Only 1 question how can you complete the deal if you are offline

And where you see we are agreed on $$$
He connected me for deal his BTC my skrill rates are 1:1 he never said or even ask that we r dealing in $$$$ etc if he want to deal in $$$ he must ask me for that but he didn't
before going to offline you should drop him a message that, "I'm going offline" or something like that. you didn't tell him anything, just left your wallet address and went way.
And it's common sense that you are dealing for $ because $ is the only logical currency that you can trade with skrill. Don't tell me that you wanted to give him skrill BTC. -_-
