That's it, let him sell if he really has it.
So maybe he has it?

I'm confused now. We know is a scammer and is not satoshi, so how can he have that many bitcoin?
Why are you too troubled about what CSW said? My hunch is that Craig Wright do not have the possession of this much amount of Bitcoin. Well, before threatening he should have shown that the amount he mentioned is in his possession. Otherwise, his threat is nothing but childish, a behavior that perfectly fits a cry-baby like him. That alone should pacify you already. And if he really does have the amount, it is impossible for CSW to let go of all of it. He knows he'll be a loser in front of the world if he does that.
