No, but not related to watch-to-earn.
In all of our video watching we have discovered some tips on how to raise what you earn.
1) Video ads roll-over/renew at 12 am Eastern Standard Time (New York City time) / 9 pm Tapastic Standard Time. They are first come first serve. If you wait too long we found there are fewer better paying ads available to watch.
2) There are two tiers of video ads. The better paying ads (limited number) run first. Then the lower paying ads run after the first tier is used up. There are many more second tier ads.
3) If you get a low payment (6x to 15x) for a first tier ad, close Tapas, wait 20 minutes, then re-open Tapas and watch another ad. Generally after doing this once or twice, the ad payment should double. We've done it to go from 6x to 28x or 14x to 32x. Second tier ads are not affected by this method.
4) Video ads can be multi-tasked. Generally we will watch national TV news while also working through our video ad quota for the day. Mass transit/carpooling is another good time to work through them, unless you use that time to read on Tapas instead.
5) If you get the gray (grey for Louis) button that says "Watch to Earn - Check Back Later" tap it regardless. Many times it will load more videos.
6) If you get the "Watch to Earn - Sorry, no videos are available" exit the coin shop, then re-enter. Often new videos will become available either immediately or by tapping the "Watch to Earn - Check Back Later" button. If not, try a second time. If still not, then there is nothing available at that time.
