People are just afraid BCH will ruin the value of their BTC holdings and will do anything to resist it. But if they can see the whole picture they will understand BCH is good for BTC and their holdings.
Just hold your BTC and BCH and you will come out on top.
I agree with you but the million dollar question is when would it be advisable to start selling BTC for BCH? When hash power directed at BCH is greater than say 25%? There should be a metric to follow that is a leading indicator of future success of BCH.
