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?
I think that coins that have already fell so significantly, are not likely to return to previous levels. They were abandoned not only by investors, but maybe by developers as well, so I think that coins that have lost their value will not worth something again. Trends mean a lot, and if there are no investors who are willing to buy, it will not grow again any more.
