I want to know mylot can really earn money?

Yes you can earn money on MyLot, the amount that you can earn depends only on your own efforts. You have to make some posts and read and rate everyone who responds to it. You also have to respond to discussions that other people start. Both your discussions and responses have to be of sufficient quality and be pertinant to the discussion, there is a bit of leeway if you reply to someone elses response. One or two word replies are not sufficient and will earn you negative ratings (which means you will either not get paid or get paid very little for your effort), as will using too many abbreviations or 'TXT' type language. You usually get paid 1 - 2c for each quality response, and I think you get paid a little more if your response is marked as best. You should also mark the best response as well (but not too soon as responses can take weeks to come in). I am not sure how you get paid for starting discussions but I think this is paid periodically (perhaps not every day). If you do this you should be able to earn the minimum payement every month. Remember though that everything you do has to be sufficient to earn enough.
