From my personal experience, this coin might be a scam because I used to mine it and also used their referral program and my coins were confiscated and my account on their website was suspended.

The reason was according to them was that my referrals were not active enough.

Then I moved to Cryptotab which is a mining browser and used the same way used with Jsecoin to send referrals to Cryptotab, and I am getting paid regularly for my referrals.
