Bitcoin gets all the news, but the best performing cryptocurrencies were the smaller Alts. Ripple (XRP) rose 36,000% to be the top performer of 2017. ETH was up 9,000% , NEM rose 30,000% and Stellar was up 14,400%
That's an impressive year for Altcoins. They will be interesting to watch in 2018 and see which coins go on to dominate.
