Somebody is mining directly to FreiExchange. Please stop. They will put a penalty on Datacoin and you may lose your coins. First mine to your own wallet and then transfer to the exchange.
I never understand why that is problem? I mine XPM directly to Poloniex, where I exchange XPM , for years and never have any problem, never have any penalty , never have any issue.
To be clear I am not that person, and I dont mine directly to FreiExchange because I always do solo DTC mining.
