I'll call it:
Saylor doing a private OTC buy.
Maybe we see this in an upcoming Microstrategy press release..
There is plenty of supply available in the OTC market, there is no need to activate a 14 year old address for this. Really why do people keep coming up with random theories that make no sense. For this case I've seen everything from Roger Ver to hacks and now even Saylor.
Just relax poor man and take a deep breath, you need it.
