Instead of answering what average returns are "possible" (since, of course, it's always "possible" to make a million a day), I'll answer what is PROBABLE.
It is PROBABLE that you'll lose money. That's what most people do.
Keep in mind that, when you are reading a thread like this one, a lot of the major posters are SURVIVORS. You don't see all the people who've lost all their money, because they are not posting any more.
Hard work often pays off over time,
but laziness always pays off right now.
