Yes, I can whole heart agree that most people fall for obvious scams is all because of their greed. They may have limited knowledge or don't at all but with greed, it was the main driven and motivate for their downfall.
Agreed with it 100%. Unfortunately most of the time people who get scammed have only themselves to blame as they don't even take the time to read the project's website and properly do their own research, which usually can tell you very quickly if the project is legit or is it just another glass bead. Another problem is not doing any research at all, and counting on people on twitter etc. shilling altcoins. People don't realize they are not listening to experts or enthusiasts but paid marketers.
