But do you think miners/mining pools will support such a chain? (Or at least most of them?) What would be the incentive for them to do so?
If miners do not have incentives anymore, then the security of the blockchain might be in danger or at least in a more vulnerable position.
That’s exactly the thing that would divide our community and could lead to unwanted increase of volatility. Not having come to a consensus, investors might not know which one to participate in thus reducing both chains’ market value.
