"As a stakeholder, I find the third scenario being the only one in which my interests are protected."

I think you will find that your "third scenario" is the least likely to happen. When it comes to Steemit, getting rid of the "status quo" is the most likely (and most important) outcome of all. It has been the maintaining the "status quo" which has put Steemit exactly where it is today...on a downward spiral into oblivion.

In order for Steemit to survive, and attract/keep new members, massive changes will have to be made. Many Steemit members already realized this fact, but few were willing to stand up and speak up, primarily for fear of being downvoted and their reputations ruined. Many instead simply cashed in and left the platform, which no doubt accounted for the rapid decline in the value of the Steem token.

I suspect that your "first scenario", an aggressive takeover, will be what Tron will implement. No doubt, there will be many long-time Steemit members and witnesses who will not like this scenario for obvious reasons, not the least of which will be their loss of power, but they have only themselves to blame for that. The writing was on the wall for months, but they chose to ignore it. Now it's time to pay the Piper.
