Although I personally like Ethereum and Bitcoin very much, I now hold Ethereum and Bitcoin, and I am full of confidence in the future of Ethereum. But Bitcoin is still the leader of the world of cryptocurrency. As for the market value of Ethereum, More than bitcoin, I really don't predict
There's no way that ethereum or any other altcoin that can surpass bitcoin.
Current value of bitcoin can possibly reached by any altcoin in the future once bitcoin is flying high and is unreachable. But what's with ethereum today, its very unlikely to have this possibility. ETH keeps on plummeting and it can possibly go lower than $100.
