It's being reported that 60k of those 80k awakened last week have been moved to OTC desks and further down to exchanges. It's far from 10%.

My point is, there will never be a "last one." Long term holders will sell forever.
In this case, let's imagine this person is selling about 50% of their stack. 60k of their 120k coins. I think that's totally rational, and we can expect that kind of thing to continue forever.
