i think a longer confirmation isnt a real Problem - becuse it hits everyone - perhaps its only a Problem for Dumping the coin but a lot of People that i know are coinholders in this one
syncing is all fine - ive tried it a dozen times with ever building a new wallet - theres no real Problem accept starting the wallet once/twice new
but perhaps it was just luck - the only Problem im still having is staking - thats like a mystery for me - it wont stake anything

confusing - and its not my first coin
the longer confirmation time, I think , is exactly the reason why you are not minting coins.
the code specifies block generation should be 60seconds (correct me if I'm wrong) and block generation is nowhere near that, in fact block generation is so intermittent that this is bound to have effect on the staking process.
This could well be the root cause of the problem.
