One thing you need to understand about microstrategy is it's kind of techniques used in buying and selling, at some certain point in time i begin to observe it purchasing pattern likely linked to DCA purchasing pattern whereby it has preciously bought some on a frequent occasions and within a short interval of time, yet it keep purchasing the dip and continue with accumulation, now that it has decided to sell at the dip and yet forfeiting the tax pay and losses, i think it has something in plan for making another buy coming this new year, maybe it sensed a drop or little more dip coming between now and January in other to have more opportunity to accumulate more, but let wait and anticipate for more coming out from them.
They can buy or sell as they see fit, but any tax benefits they thought they were going to get, they have lost due to not following the wash-sales-rules.
All they had to do was wait 31 days before buying more and their tax benefits would not have been lost.
I find it hard to believe, that they made such a rookie mistake, but they did.
If those btc were purchased near the $64K top,
then MicroStrategy just lost close to $33 million bucks in tax write-offs,
ugh, that is a very bad day.
