how many should i post to reach payout?

You know something, if you're here, you just forget about the money part and try to post quality material. There's no use being restless. Just enjoy the time out here. The money will automatically come.

There is no set amount because it depends on the quality of your posts. Higher quality earns more money. However, to truly be sucessful here you need to just build your reputation and friendships first. Making money should not be your objective right now. In fact most good mylotters will agree that the money here doesn't even matter, it's just a nice bonus for making friendships and helping people.
