I have been retired from crypto since 2017, however, I received an email from Bittrex Global a few days ago saying that they were going to close a wallet were I had some balance. This was my 1ST firstblood wallet that they freezed for no reason in 2017 when they stopped working with 1ST (that is why I had this balance, because I was not able to withdraw my 1ST back in 2017).
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.
In fact, I withdrew to Metamask and realized that 1 1ST < 0.000000001 ETH. Considering gas fee, it is not worth to me to swap my 1ST to ETH.
MY QUESTION IS:
May some day this noncirculating coins in my wallet be worth anything? May them have a future collectable value as happens with real old coins?
If you are not interested in exchanging them at all, then you have nothing to lose. Just leave them in the wallet and see for yourself what will happen in the future.
However, I think that there are so many shitcoins on the market, and more are created every day that this type of dust will simply be forgotten. However, there is always a chance that there will be enthusiasts and collectors for whom it will have some value.
