Post Body

If a fork occurs with 80% of the mining power going to Bitcoin Unlimited, won't that make Bitcoin Core blocks take 5x longer to mine, making mining them unprofitable, causing all remaining miners to leave the old chain? And then would it take months or years for the difficulty to readjust, effectively leaving the old chain totally unmineable?

How then could there be a split, short of Core forking themselves to decrease the difficulty allowing 20% of the miners to remain on that chain? Has that been proposed?
