Most big cap altcoins haven't had any real growth in 4-5 months. Its just bitcoin/forks and a few lucky small cap coins that have had growth recently. Look at the chart of the top altcoins in both /btc and /usd. Look at ETH, ETC, XMR, LTC, XRP, DASH all way down vs bitcoin and haven't sustained any growth since the alt boom in march. Look at steem and bitshares too way down.
