I have 0.1 BTC in my wallet but you must go first - no escrow because when i need them they are offline. - i prefer fast trade.
Sorry i cannot go first, i even sell them at 0.1
BTC price instead of 0.5
BTC so it is as valuable as it is. How do I know you will pay me after?
Well you could go first if you wish to try it, if he defaults on payment then his account would be worth nothing.
Many members would give him red trust, and all you would lose is one account out of the many you have.
Just a suggestion.
