Anyway, when I logged in to my old Bittrex account I realized that the wallet withdraw was available once again... but in the meantime the crypto had evolved from 1ST to DAWN. What is more, 1ST had swapped 1:1 to DAWN a few months ago and non swapped coins were put out of circulation. That is to say, my coins are not circulating and have no value.
I think you are partially responsible about this loss as you invest in projects that you are not ready to follow their updates. Exchanges are not supposed to inform you about the project updates (including blockchain swap).
MY QUESTION IS:
May some day this noncirculating coins in my wallet be worth anything?
Surely it will worth something if you can find someone ready to buy it from you. Until that time, don't expect too much.
MY QUESTION IS:
May them have a future collectable value as happens with real old coins?
This is also a possibility. But you have to be lucky enough because dead coins are almost much more than the active ones (+13k active crypto listed only in cmc).
Even so, for memorable collectibles, we have already created NFT tokens.
