The "get rich quick" attitude makes the market competitive and pushing projects to compete agaist each other. This make the market more healthy. No good wills are going to do that, only people seaching for promising projects help define the market.
partially right, but it is also the reason for making the market unstable, making most of the new small investors dive blindly causing chaos.
making the market less stable and less reasonable and responding very randomly to each kind of outer events.
