Sure he could probably return 250btc without a sweat now, but I believe the main thing keeping him from returning anything is it would be somewhat akin to admission of guilt, even though many eyes already see it that way. If he does return the coins though, it would at least be a step forward for some in the crypto-community to begin healing from past grievances.

Either way, the longer he stays in the crypto-community through his exchange, microcash or any other ideas he comes up with, the chances of his identity being revealed increases. The question is, how much backlash will he get when that finally happens?

RS, you'll probably end up reading this at some point. Return the bitcoin. It'll be a breath of fresh air to make good on your debts and likely help your creative juices flow.
