I miss the non-ref Link

As what i have observed this is the amount of bits you can earn per video

1st video = 60bits
2nd video = 20bits
3rd - 4th video = 10Bits Each

The next videos will be worth less than the first 5 videos you've watch
It will be Re-set the next day or approximately after 24hours, not sure about it.

So for the first - 4th video you could already earn
