It looks like they are following a pattern, basically because the price has been trending up since they bought their first stash.
I'm an advocate of buying a small amount of bitcoin regularly but being able to HODL what you have bought for multiple months or even multiple years depending on your end game with the budget you set yourself.
So, there are two questions: Is the MicroStrategy strategy of seemingly regular purchases an up-scaled version of what I wrote above? And, if so, what is MicroStrategy's end-game for the coins? (i.e. dump at a given price? Dump on a given date? Or just HODL indefinitely?)
