Usually I just watch this thread but the fact that Ark dropped out of the top 100 recently made me want to drop a few lines here. For me the problem with Ark is that it is so far off its original plans right now. People initially invested on Ark for the features it initially promised to bring but the team seem to have taken a large detour to get there. I feel that it will take them one to three years of Ark core versions to go back to the original plans : interoperability, IPFS, NFC, Smart Card, ArkVM. Other original plan elements (IPDB, anonymous transactions) seem to have been scrapped or set aside without it being clearly stated by the team. ArkVM is morphing into ArkLogic in the latest whitepaper. Also Ark has not had any major partnership despite FX Thoorens' ties to members of the French government. Those partnerships with big companies or governments are oftenly what puts altcoins on the map. Another point : Ark arrived in early 2017 in the crypto sphere, that's pretty late (first mover advantage seem to be really important in the crypto sphere). Even despite the Roadmap it's not quite clear in which order and when the team intends to bring this and that feature. I do want to say however that the team has kept on delevering new things and advancements steadily and that Ark is undervalued.
