How many Dollar one can earn here?

Contrary to what others believe, you can upload photos even before reaching 100 posts. You can add image to your discussion or you can upload any photos under the interest sections. However to answer your question, it's really unpredictable how much you can earn since myLot will have to determine how much they want to pay you for your posts. Apparently you don't get credit for starting discussions but you get paid for responses you get regardless of the number. Similarly of course you get paid for your responses to others' posts. I think you get 0.01-0.05 cents for responses you make depending on the quality of course which is determined by myLot mathematicians. You can look up discussions similar to this one and you will see different answers. Have a great mylot posting!

I haven't earned much here. Sometimes I only earned about 20 cents a day. I would like to earn 10 dollars a day but it looks like a wild dream now. Maybe, the day will come when this is possible.

For a few days make a note of how many posts you make, the number is by your username when you post, and how much you earn each day, it updates daily, after a few days you will see wht you earn for the number of posts yu make and then you can adjust this to earn more. Make sure they are quality posts and you will do ok. You can also earn if you have referrals and after 500 posts you can add images which increase your earnings.
