No, of course not. It would be amazing if Samsung were to buy 150m Steem. This would most def. pump the price extremely hard and I don't think there is even that much Steem available for purchase right now.
Also, this has nothing to do with Tron buying the stake or with Tron now being a big stakeholder. It has everything to do with Steemit Inc and their premise on what the ninja mined stake was supposed to be used for. If Tron bought the stake, without knowledge of what it entails, well then there are going to be some problems we have to work out.
