People are scared over the growing dominance of Microstrategy into the cryptocurrency market. But I don't think anyone is bashing Michael Saylor personally. people are worried about too much of corporate cash flowing into the crypto market. Cryptocurrency should stay with the commoners like us. if corporates start buying into this market, it's just a matter of time they will gain the complete control of it. I believe that's what people are worried about.
A lot of corporates are sitting on a pile of cash which they can indeed invest into various assets. Microstrategy has shown the way and there's no guarantee that other corporates will not join the bandwagon. I am sure you wouldn't like corporates controlling the majority stake of the crypto market in future.
This is what I think the reason why. I think it won't be good if others will follow microstrategy on accumulating more bitcoin. It would be problematic to other people who can only acquire small amount of bitcoin and as you have explained that they could have a full control of the market if this will happen. It will be hard for commoners like us when it happens when they have full control of the market although it's still possible but very hard and I think it will be costly.
