Meh, ZEN is an incompetent disaster which have only achieved ZCL crashing into mud.

Fancy whitepapers and claims, zero clue to us of what's actually going on.

Either stick to ZEC, which seems to be stable in every way and have already gathered some big boys' attention, or move to HUSH, where the devs are working calmly on their pretty clear and realistic roadmap, instead of telling us "how HUSH is different and fancy and all".
