I'd love it if zeta merged ... BUT ... they are geared for 30sec or 60sec? It's main selling point is speed.
XJO is fine on it's own at 45sec, it should stay there and has a good dev, but if the network is ever in trouble I welcome XjO to 180secs.
zet isn't doing so well with the network. Look at transaction times. Is zet really faster than Un? Not much! With the weak network they have you'd need to take 10 confirms - so do they really benefit from sticking to it and NOT merging? I think they would benefit more from merging. UNO is blazing fast with the 3 minutes and very secure. 30 seconds ZET with weak network isn't secure at all. I think they might want to consider right now. Together we stand, devided we fall
xjo is also not what you call a strong network. If that price goes down more they have some trouble. Merging Uno, Zet, Xjo will likely give all three coins more strength. Xjo could stick to their emission and pull through with their plan with no risk of fail and ZET will secure its survival too.
Just some random thought.
I think if you would announce in this very moment on the ZET and Xjo thread merging with uno these coins would jump up in value - uno would also gain some ground.
I think we should at least make a suggestion to ZET community and they have to decide if they want to sacrifice the short blocktime for more network strength. I think for them it's right now a no-brainer to do that. I hold ZET too and i would opt to merge if i was asked tbh. ZET-people need to discuss that. If they decline, ok. But let's have the discussion
ZET network currently is really weak. Maybe they are really greatful for such an idea right now?
the other ideas you bring to the table are really interesting BN
