Obviously. As long as bitcoin has a future which I am sure it has, there is always a bright future for many different altcoins(Ethereum, Litecoin, DeepOnion etc). On the other hand, the shitcoins are simply useful short term holding and not good as long term investments.
To tell you that truth mate, Bitcoin has nothing to do with the Altcoins, you see they all have different aspects and concepts in their increase in values. Therefore, whenever the price of Bitcoin goes up, it doesn't mean that all the Altcoins will go up too, it is most likely that some merely as popular as Bitcoin will have the most out of it, what I mean is that they will have the chance to get rise in their price as well.
But if somehow Bitcoin drops its value, then again it doesn't mean that the Altcoins will also drop its value, instead somehow some of them will continue on increasing. And you know what that means? It means that they will somewhat have the opportunity to even replace Bitcoin in the future, its just that Bitcoin has all the relevance it needed right now, but it won't last as you think it would.
Well basically, what I'm trying to say is "think again".
