Actually, I think it's perfectly healthy.  I am not afraid of my coins losing value to new more competitive coins.  I will simply keep my stake in the best coins.

This is the free market at work, combined with open source software.  The coins are like organisms in a rapidly evolving natural selection process.  Only the fittest will survive, and these coins will have the best properties for an online currency.

Everyone knows crypto currency will be the mainstream.  The process by which we get there; however, may surprise you.

I personally like this natural selection process.  And, while the new ideas are brewing and evolving, it's only natural people will tinker and invest.
