At this point, MicroStrategy buying BTC is like your uncle topping up on snacks after the party started. Dude’s already knee-deep in the chips.
Anytime microstrategy buys Bitcoin it always becomes a news and it is now getting boring, what this will mean is that microstrategy will keep on taking the major relevance in the Crypto-currency market, it's good right now because it is creating a buzzing for the market, but have you wondered what will happen if they started selling their Bitcoin
They do not seem to be planning that anytime soon but should they do it I hope they have enough sense to not dump it all at once. Anyway it can get boring at some point but it might also create urgency in investors to want to buy bitcoins asap.
