My guess is eth. BTC is taking a big hit as we speak...
I think this year no one can beat bitcoin. He will always be the king. As you can see the market when bitcoin drops all altcoins drops too. So no one can beat bitcoin this year. But we don't know what will happen in the future.
my vote is for bitcoin too. No coin is even near to beating bitcoin. It is beyond the limits of others, far above than what other coins can even imagine of. Ethereum, which has been in this try since beginning, has failed pathetically. If the king of altcoins cannot even stand against bitcoin, how can we think of any other digital coin strong enough to overtake the crypto King? Bitcoin is truly unbeatable and the best of the bests.
