I'm afraid of the coin miners. With virtual digging capabilities - also known as a hashrate - is increasingly concentrated on relatively small holdings, which may increase the risk that diggers will jointly perform attacks to make up 51% of control. Transactional activities or code changes in the blockchain to their will.
First off...and semantically writing (speaking), Miners isn't the same thing as
Minners.
Now to the BOD, the synergy you envisage isn't what I feel would be tenable. I don't think miners will have that sameness of purpose and decision to pull that majority stake to hold the rest of us hostage. We saw how divided they were and have always been during the previous forks. Off course, if they had all put all their heads together Bitcoin would either be dead or not have had any forks at all. So, 51% controlling stake isn't possible.
