I don't think there will be a new coin like Bitcoin with a decent supply curve and deflation, because new coins to enter the market are very difficult. I think XRP can be silver2.0 or copper2. because the coin has a large volume and a clear concept.
all depends on the market concept that is running. now bitcoin is the biggest and strongest. concept in the market and trusted by everyone like that. but when there is a change in concept, investment and trade will change. all depends on how the market determines attitudes.
