All this stuff is scam stuff best to just bet money line on sports at a good site you have a 50 50 chance and its fair
if you use it without greed you can make money here too
or you can loose money in the same way...
but greed, thats the point! to many risking more as they are able to loose, because they want more as they deserve. most of them think they can get rich quick and without much effort.
and if they have lost all, they can't make money due to this! independently of the greed.
and finally, games are for fun, not for making money, even investor based game not! and if the game offer a other suggestion, then is it not a fair and honest game!
