Say, one has ~250K coins, and needs to return 300K during the next week.
Say one sells 100-150K coins right now in this highly elevated price.
Will there be enough panic to get the price back to say 8, where one can buy at least 200K coins?
No.
who's going to panic sell below 10?
we all know theirs a guy out their that wants to buy ALL the bitcoins
Well actually the guy might be willing to buy them if he cares more about his reputation than few (hundreds thousands) bucks. But, than again, he might be just waiting for a new yacht at that time...
