I completely agree, I also think that 2018 will be a breakthrough for many altcoys, it is no longer surprising to hear that in this or that sphere they are implementing a blockade and signing a contract with some kind of coin. Many altcoins are undervalued at the moment and as soon as the market turns around, they will fly into space.
I do not think there will be strong growth this year. On the contrary, many individual coins will die. Total capitalization will not grow, it will be redistributed between existing coins.
