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.
Of course, altcoins really have a future, there are so many living proofs that people quit their job and just enjoy their life because the growth development of altcoins, trust me, altcoins will shine and rise again in the future
