245 BTC is actually not the lowest purchase for year 2025 look at their portfolio tracker https://saylortracker.com/ you can see on last March 17 Microstrategy bought 130 Bitcoins.

Also on March 19 2024 they bought 33 Bitcoins so that last figure they buy is actually not surprising if you are following their purchase thru their tracker.  So provably there's good chance on their next accumulation they complete the 600k Bitcoins holdings for their company. So far they are doing good with that and somehow curious get some update on when they announce to purchase more bigger volume and hit that numbers speculated by people.
