Payouts are too low. Bit777 is offering 0.5 for the maximum threshold of 2000 posts.
0.4 for 2000 non spam posts is not gonna work.
I'm sure it'll work fine. There's plenty of other options for sig deals that pay less than both and people still choose to use them.
Note: Payouts can change at anytime depending on BTC/USD rate.
This doesn't give me much faith as well.
Do they pay?
They appear to be legitimate.
