look,
you keep polishing your story, but only when I squeeze a bit more,
I stand same ground from the beginning
There shouldn't be any need for him to polish more or for you to squeeze more. You are being belligerent in a way almost everybody reading you is going to think is unnecessary and counterproductive. I know I certainly wouldn't make any agreements with you after seeing all of this. They way you are handling this is something I would want to avoid dealing with at all costs, and I'm sure lots of people feel the same as me.
I agree. After seeing how he is handling this situation I would not deal with him period, even if he were to send goods/money first. He is taking advantage of someone who values his reputation a lot and who could potentially go to jail (for longer) if he is labeled as a thief/dishonest.
You also need to remember that you probably would not be able to sell the coins period without him as there is really not another realistic way of doing so because you would need to send first (and risk the buyer not pay, or make the buyer risk that you not send the coins after paying. I don't think any escrow would accept this trade because it would be too difficult for them to resolve any disputes, putting their reputation at ridk.
I could not agree more.
