There are people who are more concerned about what the future brings and Michael Saylor is one of such people and that's why his company keeps doing the lump sum aggressively, with the way Bitcoin is heading, I believe it has the potential of achieving Saylors dreams which is the global money of the future. However, on a second thought I think Microstrategy's aim is to continue being the company with the highest holding Bitcoins and that's why they keep pumping more money into their portfolio, we've seen how their stock price has risen since when they started investing on Bitcoin and I think other companies, institutions and firm would begin to emulate Microstrategy if some haven't started already.
