Is this good or bad mold?

I have a com-pot Indoor composter (its a hungarian startup's product). A few days ago, mold started to grow in the compost, and I don't know If I should through it away or I should keep going. Do anyone of you know if it "good or bad" mold? (This composter is basically like a worm composter but instead of worms, it uses bacterias and other microorganisms)
