The "dev" was not active for almost a month now. Why are you still interested to list this coin? I hope your exchange will not be full of crap & scam coins later on. You should have at least a good list of criteria before accepting an altcoin in your exchange.
Hello Twinkledoe,
Thank you very much for your advice.
To be honest I did not properly check the project but no worries at the time of listing any coin/project there will be an audit.
Again thank you for your advise, really appreciated.
Best regards,
