yes, child_harold was one of the bigger sellers. In the early days he organized a "swap" with CfB. So CfB should know his seed. If CH won't come back, maybe CfB can freeze this seed and transfere it to the foundation fund. That would be a small
satisfaction...
But there are still a few days for the mainnet launch. Maybe he'll come back. Let's keep fingers crossed.
I tried to contact CH as well and unfortunately he did not reply. I still hope as well that he may come back here.
Maybe there really is some way to somehow "freeze" the known part of his IOTA as Come-from-Beyond suggested it by changing the snapshot before the launch until the case is solved.
