I think they're waiting for V2 to be finished.
Ark Core v2 is now at 93% finished, this is a really great step I think price will go up when v2 hit the devnet and people can see it at real time.
Where did you get the information about 93%? On the official site, in the Roadmap section - still ARK CORE v2 = 71%.
If you click on the blue title "ARK CORE v2", the "Developing & writing ARK CORE v2" is on 93%. I guess that's the percentage he mentioned, but the overall 71% would be a better indicator.
Nevertheless, let us remember those percentages are changed manually by the team whenever they feel like they've done good progress. They might suddenly progress faster or they might hit a wall that'll delay them.
