3. This split can be expected to spread to Bitcoin. If DC fees dominate, the race would otherwise be won by the fork with more valuable DC transactions, regardless of whether it maximizes bitcoin value or not.
Bitcoin transaction demand ≠ bitcoin demand.
4. I tend to believe Bitcoin would likely split in 3 in such scenario, as some holders may prefer to remove DC induced risk altogether and disallow Drivechains (potentially dominant hashrate escrows in general).
