But if the discussion isn't tied to specific altcoin, then Serious Discussion should be okay.
I believe the OP meant, not tied to Bitcoin and hence can not be posted in Bitcoin > project development.
And serious discussion has a strict no advertisement policy.
Hey, I'm a developer working on some new tech. I was hoping the discussion forum would be talking about the pros and cons of different consensus algorithms, possible attacks, etc. Instead it is people freaking out because prices are down.
There are still posts I see there which borders on the technicality of coins. And you can always add yours to the mix,as there is no other suitable section
