I believe Bitcoin has a future in long term. It proved itself in the past years and it is getting widely popular. It just has a transaction fee problem atm.
What about the altcoins? Who does use them for real? Will people use them in the future for real purpose?
I only have a hope for ethereum and litecoin, but not for the rest. I am not even sure for eth and ltc.
If bitcoin solves the reansaction fee and time problem, I doubt eth and ltc even have a future.
We can not say for now that other altcoins has a good future, well all altcoin came from below same sa etheruim and others but look at them now, we are having faith on them for the future, all altcoins has possibility to grow, and be a great coins.
