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.
For me its yes, although a lot of it are just shit coins but there are still coins that are successful that have a future. Just like ethereum. That is a very successful altcoin and for me, it had a lot of potential. In fact, I see bitcoins in them before, but we all know that ethereum cannot surpass bitcoins because bitcoins are too far to reach. They might inflate as rime goes by but if that happens bitcoins value also inflates. But when you talk about altcoins. That would be ethereum, a great investment for me if you are looking for altcoins.
