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.
I believe etheeium or other altcoin can reach the value of bitcoin it is just a matter of popularity and the accessibilitt to the mass. If the currency is not helpful enough it will not be popular and it eill not gain enough people to support it. Imagine if you can persuade the audience of bitcoin into spending time in a single altcoin. Itll surely make a change
