Seems obvious ETH will be bigger than BTC but that isn't saying very much. The question is will EOS, Tezos, Qtum and others also get bigger? I would think we haven't even started to see how big it is going to get. Next year is when the real bubble will begin if this is one, as we could have ETH in the hundreds of billions market cap and the space could be approaching the trillion dollar level. That in my opinion is a true bubble.
