I agree, for now. What I was trying to say was that I don't think that'll necessarily be the case in the long term. Cryptocurrencies are a broad field, and I believe that BTC is big principally because it's the first success of its kind, not because of anything inherent to it, and I do think that in the long-term currencies like ETH will be on par with or valued higher than BTC because they're founded on strong ideas of their own.
