Yea conducting this op at all seems like it was always going to be high risk low reward unless its a state-level actor, and if it was I doubt they'd return anything.

I suppose if their reward is in ruining blockstream, under the assumption they can't get away with the proceeds, then they could send the coin to a burn address.

I'd think it more amusing to kill 2 birds with one stone and send it to the Spark statechain and pop that delusion when they recover it.
