Personally, I'm more interested in what innovative developments will result from this coin like the incorporation of ICG into ATMs that you mentioned. The price has indeed shrunken, however I'm confident in the ICG team delivering upon the developments which were proposed earlier. It is after all a community effort so it's always possible for volunteers to innovate and improve this coin. Future relevance would depend on community involvement and interest which so far seems to be growing.
I agree that ATM integration is a major feature and in my opinion it should be further utilized by increasing the amount of ATM providers accepting ICG. I was thinking of targeting untapped markets outside of Europe and the U.S.A by patterning with foreign companies seeking to provide alt-coin payment solutions either for physical locations or for web merchants.
