I'd be vary of such orgs coming into btc trading... Sorta defeats the purpose of it surviving as a currency and only as a trading mechanism; which is not what it should primarily be.
Wary you mean? The bitcoin network actually needs companies like MicroStrategy and even bigger ones to join the network, I don't see any cons in it, it appreciates adoption and encourages other establishments to also come in. Btc's purpose btw isn't to survive as a currency, and I don't think it matters at all what people or establishments do with btc when they buy it. That being said, if bitcoin is to serve as more of a currency like you said, more adoption is of course needed and that can only come with more of this kind of news.
They ain't contributing to the network; I don't see them mining; just PnD. Declare that u r buying to pump it and then dum when u see sufficient pump. Adoption isn't PnD.
