Activity is down massively
This is a terrible indication of health of the ecosystem. Hive needs to grow massively to enable it's real strengths to emerge. The things that prevent growth, even cause users to decline, are the result of the plutocracy increasing their acquisition of more stake, which is why the witnesses and devs they control are not revealing any alarm. They're doing what they're being paid to do.
If the price drops by half again, I don't think Hive will survive. The witnesses will do better tending bar than running nodes, and the whales will have accumulated stake until there's no market for it left, and it becomes worthless.
User retention must improve dramatically, and the only thing that will improve user retention is the whales decentralizing stake so new and present users will have incentives to join and stay on Hive.
