I'm not sure how to consolidate HAL and PXC into a single project unless to discard both of them and launch a new one with coin exchange. I see many complications on this way.
I think that is the only way.
Snapshot marketcaps on random day. Create new coin swap accordingly. I think there are many scripts for this or nova can do it quite cheaply.
1 new project to focus all improvements and updates. I think a single dev no matter their skill can only successfully manage 1 single project.
ORB is not really worth it since the history is so poor and if it ever gets to a large cap it will just bring out the haters.
PNX and HAl are worth consolidating.
Rebrand could be considered too although I do like the name halcyon.
This is an alt coin bull run right now a huge one and I think it has more legs left too could run for another 3months or couple of years.
