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.
This is becoming an interesting thread...Yes, altcoins have a future, a very bright future. It's a big world and the need for cryptocurrencies will only grow. Bitcoin will always be on top (or near the top), but in a diverse world you can expect there to be diverse demand for different cryptocurrencies (even if they are similar).
Competition is always good and consumers having a choice is good as well.
Hardly anyone believed in Bitcoin when it was introduced, many people called it a scam...people called Litecoin a copycat scam and attacked the creator...and look what they are now...and EVERYONE is jumping on the blockchain bandwagon.
Just thinking about how bitcoin has changed the world...I want to buy Satoshi Nakamoto a beer, make that a few beers!
