this is not correction its the Charls Darwin theory : the weak one dies , only the strongest survive

May be this theory too.. this is valid for all coins out there.
People are greedy to earn profit thats a reason they sell there gvt to bitcoin they dont understand the good potential of gvt.
I believe in that theory this apply to all cryptocurrency coins are die because people dont trust the project and coins are survive and continue to growth because people still believe in project.
