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.
Why do you think Bitcoin has a future in the long term and not alt coin?
What can bitcoin do?
You do not seem to have a basis for that argument other than it is popular.
I do believe in Bitcoin but i think altcoins like Ethereum and Neo will be even more important in the future.
And there are many altcoins that have applications beyond just storage of value.
