MrCrank, it do not work like that, market price do not determine how currency is going to performance in future. Circulating supply of bitcoin Cash is smaller compared to that of ethereum.   You should understand that coin in circulations contribute to the pricing of the particular coin. Ethereum has a stable price and in future it will definitely going to outperform others coins. Bitcoin Cash on the other hand has fell drastically and ethereum has the opportunity to excel in price than bitcoin Cash if you check the trading volumes across all the exchangers platforms.
