Since their start in August 2020, Microstrategy has bought a total of 189,150 BTC. It's certainly uncertain if Michael Saylor is slowing down soon, given his understanding of the importance of long term investment in Bitcoin. Microstrategy's current Bitcoin accumulation worth over $5B,
If we are to work with the figure you just gave above as the total amount of Bitcoin Microstrategy currently has @ 189,150 BTC, then I think with the current price of Bitcoin at $43,100 per BTC, then it's accumulative worth is actually more than $5B, as it's currently up to $8B (i.e 189,150 x $43,100 = $8,152,365,000). Hence, this should be a sign for us all to keep accumulating ours just as Microstrategy has done theirs, if we really wants to reap good profit after the price of Bitcoin start skyrocketing after next year's halving.
