ETH or EOS might be good by next year
I don’t think so altcoins have this much potential. Even if these coins rise in value, they won’t by a great margin. Many people have switched to bitcoins leaving altcoins which is further making tough for the altcoins to touch the sky. I believe altcoins got to work hard before producing profit.
Well example: Ethereum and STRATIS after one year crowdsale, they are increasing and growth very fast and reach to highest price, so I think an altcoin potential is altcoin still young, listed exchange or don't list but team devs always support and update any time for community. They are really project and promising.
