before 2018 it might be unlikely. BTC has all the attention right now and will have it for the following coming months. There are some interesting things planned for BTC in December, such as the CME group integrating BTC futures which might attract some serious attention from institutional investors. Altcoins will definitely suffer due to that, but it's not expected that it's all too bad. Once the hype around BTC and the institutional integration has passed the Altcoins will rise again, it's just a matter of time. Be sure to be invested in either way, so that you might not lose some potential gain from this (it might be that the futures integration from CME will drive BTC's value down, because investors will now have the option to short BTC futures, or bet against it in other words).
