It is really hard to predict the future of altcoin, but I think that by the end of the year the market will recover slightly and ETH will grow to $ 800, BTC may exceed $ 8,000. And I do not think the market will increase strongly at the end of 2017
You are right, and I think the main factor that makes the market difficult is the number of altcoins, this makes the competition very tight and difficult so that many altcoins die.
