It has taken him over 2 months to dig up an estimated 34% of the wallet he is working through. The rate of digging has slowed during that time. At the current pace the digging could continue for another year. And then he could start on another wallet.
I don't see the price recovering any time soon, but doing anything to address the issue seems to be unpopular so it looks like we're stuck with things how they are.
Thanks dooglus.
That was a little worse than I had thought - I had expected he'd be done by the end of this year. I'll keep checking this thread for updates.
