There is lot of old coin gonna be useless if they dont evolve to handle current trend and tech, most likely they wont, changing protocol need to rewrite from beginning so these coin gonna be forgotten and pumper likely they will create new coin
But XRP has different problem as this is being sued and up to now facing cases from SEC in which makes investors leave and find other currency to invest for.
protocol is easy to change after the case wins but what if not? what if this continue to run for another 10 years?
xrp will die without even changing.
