At least you were blessed to have a name and a face associated with your heist.

I'm continually reminded how some are left holding air with only an avatar as their description...lol...funny; but not really...

Best regards. It's best to let the BTC loss 'go'; but, stay alert on protecting yourself and others of bad actors on the landscape.

As you said, a gentleman's apology would end this; but, until he desires to make his reputation in good standing, if not by monetary, apology at best, he will continue to pop up as a shady dealer.

Hopefully, he will turn the ship around. He sounds like an otherwise pretty 'talented' being.

Peace.
