An interesting approach to write a simple statement, without proof. Even if you can see the future, but for some reason did not see who will replace Bitcoin? In principle, it is unlikely to be a replacement for Bitcoin, as this is the first coin and the progenitor of all, I do not think that it can be replaced in history. And even if a certain coin will be able to escape to the first place in capitalization, everyone will remember Bitcoin. On the other hand, I don't think that EOS or Ethereum will die, they will stay and compete with each other, despite all their shortcomings.
