Their blockchains are shorter. Longest blockchain always wins in the long term -- that was proven in the Bitcoin paper.

  Which Bitcoin paper are you talking about? (Do you mean the original white-paper that introduced bitcoin?) I'd be very curious about any such proof comparing different crypto-currencies. I can't imagine how that one would work. Do you mean a mathematical proof?

    Yes, in the original bitcoin paper. The blockchain with the longest proof of work is always the real one, given multiple competing blockchains. That’s literally the whole point of blockchains. It’s like Highlander, there can only be one.

      That's not a proof in the paper. That's a definition of how the system is works. And it's only part of the procedure for how to choose between different competing capital-B Bitcoin chains. It doesn't say anything about comparing different coins.
