Do you believe they (ancient coins) should change to keep up with the new trend?
I do believe but don't you aware that if those old coins have a second layer solution that have already been implemented? I meant it's not all old coins could not able to be used to issue the NFT. Some coins like bitcoin already had a second layer solution like RSK, lightning which make it able to be integrated with the NFT trend.
Some people may not agree with this idea but the old coin must follow the trend to keep its demand and volume. People were actively rushing from one to another coin.
IMO the old coins must be able to adapt to the trend that was happening in the cryptocurrency ecosystem. This will be making people will not leave it.
So many old coins became dead coins as people were migrating to the new protocol that was offering more benefits for all of them.
