If i see the graphic for the coin's price in the coinmarketcap, the altcoin that will be grow and have brigh future to investation are eth, neo, lsk, mkr, nano or waves. Eventhough most of altcoins have price's decrease, include the coins that i suggest, but the decrease of that coins aren't drasticly and the coins more valuable. Hopefully the market will in good condition and the value of coins increase.
