They have ONLY been accumulating, and pretty regularly since the start of this thread... including saying that they are never selling.. even though they might be exaggerating a bit on the last point.. perhaps. Saylor is so crazy, he might really be telling the truth about never selling, even though he surely has the option to sell at any time that he wants as long as he is not breaching his fiduciary duty to his shareholders who might have become reliant upon his ongoing, persistent and consistent statements that he is never selling any of his (MSTR's) bitcoin.
At this point I guess never selling has more to do with Stock valuation rather tan Bitcoin Valuation.
At the moment, Microstrategy has a record valuation as its enterprise value is more than 2.3 times the Bitcoin they hold.
Selling bitcoin from Micheal Taylor would have a negative price impact for Bitcoin, but it would also destroy this "Microstrategy Premium", so this not going to happen.
Also maybe this si the reason MS has been selling Microstrategy shares lately, and not bitcoin.
