Bitcoin cash is supposed to be more efficient as it allows more transactions per block than the original Bitcoin. Different from the previous challenger Ethereum, the similarly structured Bitcoin Cash implies that the old Bitcoin community can move to the new Bitcoin environment at ease. Once the current rally in the price of the original turns around, existing miners may find it more profitable to switch to the other Bitcoin. More importantly, following the BoEs argument, the lower cost of transaction translates to a lower marginal cost, thereby the inflexion point, where marginal revenue equals cost, may appear later than the original Bitcoin. Hence, Bitcoin Cash would survive longer with the lower transaction. After all, the blockchain is said to bring about security, lower cost of transaction and, above all, efficiency.
