I've been following the case of dread Pirate. The btc in the sr1 wallet where confiscated by the US government. Does the guy still own the rest of his btc or did he surrender them over? From what I remember, he had loads of them. Like 5% of the total available supply at the time
They were all seized IIRC. Also, there was cases against officers who stole some of the BTC seized from him
