Did you (nachius) do the same thing to this poor guy?

The fact that you intentionally lied to these people that'd you solo mine (and thus exaggerating the required price way above necessary), pulling $500+ for a much cheaper btc.com push and attempting to justify this makes me question why you're on DT2.

IMO, the fair resolution would be for Zaizoun to pay nachius the amount required by btc.com to confirm the transaction.
