Honestly I don't think we can talk about their fate anymore since their chances of getting back in the track are extremely low. There is a reason why the price of those altcoins is so low and that tells to the people they did not put all their efforts into that project and they've failed to achieve what they wanted. Unless a miracle happens I don't know how such projects could start growing up again.
I think that today we are not talking about the value of the one and the other coin, their future prospects. If the project has real prospects and will be in demand in society, then with the restoration of the cryptocurrency market the prices for coins will go up anyway.
