He is a very smart guy. I've seen some podcasts with him and I'm impressed. I like listening to smart people because it makes me smarter. I've seen some people on here bash him and I'm not sure why. (There are also very smart people who don't own bitcoin, or are anti-bitcoin - the more opinions you are exposed to, the better).

Michael Saylor is good for bitcoin not because he holds a lot of it, but because he has a large audience and an ability to orange pill some of them. He might choose to dump his position, and while it may affect the market price, it won't affect the properties of bitcoin that make it a desirable form of money in a free market. In fact, Saylor's job is to provide value for his shareholders. His company has an actual product, and it isn't bitcoin. If he found a way to grow his business I would be very disappointed if he did not use some of his bitcoin to pay for whatever he needs to pursue that business opportunity. In fact, selling that bitcoin would be the best demonstration that it is money.
