Do whatever you can do to reach your life goal. In this kind of state the natural selection will come into place. All alt coin that not giving any benefit to the masses will die surely!
The concept of natural selection and survival of the fittest suits the animals better and we the humans are a step ahead of these concepts. What I want to say is that the survival of the fittest and the eradication of those who are unfit and who many among us think should not be selected by the nature is a vague concept.
I believe that we all can play important roles in educating other if we are able to do so and if we are selected by the nature. So achieving the goals of life is not a very big deal as long as you recognize the purpose of those goals.
