What I really don´t get.
Shouldn't avoiding a chain split be the absolute top priority?
I cannot really see a scenario where both coins combined (after a split) will be worth the same as the single coin before.
So users and miners should do everything to avoid that.
Yes this is not only true but utterly obvious.
However, we are dealing with human nature here.
We are currently at the chest beating stage of the consensus process (see link below for details)
