Did you swap your wallet back in 2014 from the PoW to PoS? If not, they may be but once again, the Dev team will need to validate that.
No I did not change from PoW to PoS. I got these coins as a long-term investment years ago and thought they were safe in my wallet. Which dev is still active and could I e-mail?
Neurocis is the Dev, check page 1 for contact details.
