Darkcoin has a lot of scam features; and was just a short term 'investment'; Doge is fair and may growth again on a long term perspective. Indeed 2013 coins and before may have a great new life,most of them are scam 'improvement' free (premined, instamined, masternode implementation, IPO/ICO and so on...); But anyway I doubt that many 2014 coins will stay in our memories; Indeed a lot of 2014 coins, and some exchanges, are involved with what happened: a trust issue with investors and miners.
