what will be ideal number of posting or reply for day to achieve $1

My sister did 100 posts one day and got over $1 so I'm not sure what's the magic number.

I made approximately 75 posts yesterday.Now,I am waiting for updating daily statistics.After I get it,I can tell you my magic number if I earn over than 1$.I believe my post quality is high.I don't even leave my words with one or two words.I prefer to write 6-7 sentences for each post I replied.In my opinnion,80 standard post would be enough to reach one dollar a day.

i don´t know :( i´m a new member
