Well, this year has been a "hell of a year" for us. Coins that came into the system this year have suffered the bad of fate but in all things we should be gkad we're still hanging around. As for predictions, if only the bottom everyone is talking about is true, then we'll be good to go in no time.
if by "coins" you are talking about all the altcoins, then it is not a new thing and this year was not an exception. it was actually repetition of all the history of altcoins. new shitcoins created every year. most of them only live a couple of months on average before dying. and last year we had a new phenomenon called ICO and it introduced hundreds of tokens which mostly started their dumps this year and many of them are already dead.
the "bottom" everyone is talking about is bitcoin bottom not generally. and for many altcoins this bottom is 0 not the current price as we have been proven multiple times so far with dumps that keep happening.
