There are so many deals on alts even now when were a little bit up from a few months ago, even if you get an alt coin that is up about 20% in the past month there is a lot more to go and as we get closer to the end of the year our chances to see some price action is growing.
it all depends what your game plan is and how long your planing to hold your coins, there are some coins that will die out i'm sure but if you hold some promising projects in your crypto portfolio than the long term will defiantly pay off.
i'm sure everyone remembers Bitcoin did not start at $5800 and so does apple, amazon, Alibaba ....................... 
you have to start somewhere and if you have strong foundation and good tech that can be used in real life cases to better the results and costs than i doubt it will die out as there is a lot of room for a few hundreds of legit coins that will be making it and i'm talking about 10 years from now if not more, for the time being were about to get into a little bull run that will make some people happy.

Happy trading everyone
