Of course these coins will last up to 5 years to come, in fact they will last forever. ETH, CARDANO, POKALDOT, TERRA LUNA, THETA and Avax coins are so popular that they will last a very long time.
There is nothing to worry about if we already have the coins as mentioned above, I suggest holding them for a very long time because ETH, CARDANO, POKALDOT, TERRA LUNA, THETA and Avax coins will be more expensive in the future
