I do not expect Bitcoin Cash or Monero to ever surpass Bitcoin (BTC) all time high price (over $100K) but both already surpass BTC in every day on-chain usage (purchases, private non-investment payments).
Just like physical money historically had three major players: gold, silver copper - crypto-currency is likely to have a top 5 where people choose their top three out of those for their desired purposes. My prediction is that Bitcoin Cash and Monero are likely to be in that top five.
