I give up on this coin, I'm about to dump everything I have. All of my staked coins from the 26th until now seem to have all been orphaned and I have lost the staked coins and the earned interest.
Orphaned POS minting is like orphaned regular mining. So called "interest" is blocks like mining blocks. If you got lots of stakes without entire confirming of entire network that's mean you got isolated. It's like regular mining after launch. Most people complaining about lots of orphan at start any coin. This was happen after 1440 block. - everyone's unlocked wallets makes swarm of own blocks and puff.
Everything seems working now.
