With all the alts out there Bitcoin still commands >99% of the market share. The free market and network effect have already essentially recognized a single cryptocurrency.
This is not an argument, it's just a statement. I can only reply that the free market can easily pick a better solution (it usually does) and mass-migrations of networked users are not unheard of.
Converting one to another was trivial.
Right... Tell me more about how "trivial" it is to convert currencies even today
Actually no, I am done here. You seem to have exhausted all the reasonable arguments
In the past all the currencies represented different weights of gold. They were essentially the same currency.
Today that is not the case.
