If we don't have 1000 members in twitter and facebook account then we are not eligible for that?
It really helps for everyone to read the whole post.
I quoted it for you to understand the op.
500 minimum, at 500 you'll just get 0.00004375 BTC
-500 Minimum means 500 minimum in a single post, if you have 4 twitter accounts or facebook accounts with 125 members each for a total of 500,
you reach the minimum eligibility for payment
