how do you know whats real

[godsservant]

The video on this site defiantly helped me to be more aware of scams but I am still running into a lot of sites that offer and say the same thing and they end up wanting to sell you something just to make a buck or two. It's really hard to tell what's real and whats not from the beginning. I dont want to waste my time on something thats not accurate. I am willing to do the time but not for nothing! can anyone help me understand what's real and whats not?
