Eventually ETH will match or surpass BTC maketcap. Just like Facebook surpassed Myspace. It won't happen overnight, but 1-2 years is a safe estimate. It all comes down to tech fundamentals and the development community. There's a reason why developers are flocking to Ethereum, and why Bitcoin can't even agree on simple protocol upgrades without having to fork.... Of course, nobody really knows for certain what will happen, so take my comments with a huge grain of salt... But to me the risk/reward is very clear and favorable towards ETH in the long term.
