777Coin campaign is changing payment rates from next week. I can honestly say that this campaign has become the worst paid campaign I have ever seen on the forum.
Taking into account the current Bitcoin value, a Legendary / Hero member's post earns you less than 25¢, meaning for 20 posts (which is kind of average in signature campaigns) you will earn a whopping $5 / week (even less for lower ranks).

I recalculated the payment taking into account the maximum possible paid 60 posts + 15 bonus posts in this campaign and this is what happened:
Tier A)
Hero - 0.00093 BTC\Неделя
Sr. Member - 0.00078 BTC\week
Full Member - 0.00072 BTC\week
Member - 0.00072 BTC\week
Tier B)
Hero - 0.0007125 BTC\week
Sr. Member - 0.0006225 BTC\week
Full Member - 0.0004875 BTC\week
Member - 0.0004725 BTC\week
Tier C)
Hero - 0.000615 BTC\week
Sr. Member - 0.000465 BTC\week
Full Member - 0.000405 BTC\week
Member - 0.000315 BTC\week
Tier D)
Hero - 0.0003975 BTC\week
Sr. Member - 0.000375 BTC\week
Full Member - 0.0002775 BTC\week
Member - 0.0002175 BTC\week
It turns out that the maximum payment for the highest rank in the highest tier for 75 posts will be 0.00093 BTC, which is ~ $ 36 at the current rate. Not a bad indicator, given that recently many campaigns have paid Hero \ Legendary for $ 30-40, and the minimum payment for a member from tier d will be 0.0002175 BTC, which at the current rate will be ~ 9; for 75 posts.
You are wrong to call this campaign the worst paid. The forum has much lower pay per week than 777Coin.
