In my option, ETH will increase faster than BTC unless coming lightning to BTC. ETH is really fast and BTC is slow. We will see what will happen
I am a holder of both ethereum and bitcoin, but i think bitcoin is we will still the best this year 2018, and i am confident that on march bitoin is we will start to rise, but for me ethereum is we will remain as the best altcoin.
Both affect each other, BTC price down then ETH follow suit.
very nice holding both, some people predict BTC will return to the top. maybe for a start of $ 10K, and ETH will follow suit.
