wont shareholders of this trust crush the marked as soon as they can sell? even if only 5% want to sell, thats 3500 Btc :/ And pretty sure some want to secrue nice winnings
Given current user expansion rate of 30 to 40% per month, I don't think many would sell.
Eventually, I think we'll be left with a few very large investment trusts that are open ended, holding most of the bitcoins. When a large sale needs to be done, it will most likely go off market to avoid damaging market valuations.
This is how large holdings of gold work today. Governments sit on most of the gold and they trade off market for very large transactions.
I speculate that the FBI bitcoin stash will form part of the US government's future permanent hoard.
