Is this coin is still circulated on the market? seems that the development has been started on 2015 and it was 5 years from now, and also cpu mining is now in the brink of faceoff because so many coin now offered a mobile phone mining, so I wonder if this project still attract miners up today.
Gapcoin should be listed (re-listed) on additional markets in the future.
At one time this genuine altcoin was listed on coinmarketcap and traded with relatively high volumes on Cryptopia, Poloniex and other exchanges.
Gapcoin was de-listed mainly due to a lack of continuing development and perhaps some uncertainty and clarity in regards to the project being stalled and/or future proof etc.,
Useful proof of work (finding prime gaps) helps to ensure that Gapcoin has a practical purpose and a longevity above its market (monetary) function.
