As I see it, some coins are definitely going to kick the bucket, and when I say some I actually think that many of them are in fact going to die soon. Some coins, for example, Litecoin, and maybe a few others (apart from Bitcoin obviously) have a strong usebase (if I can call it so), and theoretically, their price should eventually stabilize around their value determined by that use and real-life application. They are not gonna die. On the other hand, coins which are utterly useless, with their sole mission consisting only in being sold and bought for speculation, all these coins have small chances of survival, especially if things are set to go from bad to worse and from worse to worst. In fact, they are all gonna die one day, sooner or later, but the down market as of today will greatly facilitate their final downfall.
