He hasn't been online since April this year so not sure what you should expect. I don't think that it's much of a worry to you, $625, as you already own a much larger business that has hundreds of BTC in volume each week, but I understand that you don't want him to get away cheaply... Good luck with getting him to repay i guess.
I mean it's not the end of the world, but in the end it's still $625.
I have his place of work and personal details. I'm really just hoping he comes by, visits this thread, and makes things right.
I really don't want to potentially ruin someone over a mere $625.
