No, the mistake was on my part. His offer is 750 bitcoin today for 1`000 USGavincoin in the future, which is essentially the same as trading 750 post-fork bitcoin for 250 USGavincoin. I might be willing to offer you a better deal, but I will not agree to "refund" in the case that the fork doesn't happen. That's the whole point of making this kind of agreement. I'd be betting that the fork is not successful, whether by being crushed on the market or by not ever happening. If you're really interested in buying some discounted coins, you had better get in the WoT.
