More Bang for your Buck.
instead of watching videos as you do your dailies, do your dailies and the other daily objective for the safe room without watching any videos. Once you’ve done the objective and your dailies collect your reward. It will be 0 if you didn’t watch any videos. Then watch all the videos you can after and only after. For some odd reason you will get way more unknown coins. You can go from 3000ish a day to 8000. Also I would like to credit my fellow clan member “Zaphod”. They figured it out and told me how to get unknown coins per day.
