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.
absolutely 100% altcoins will have future. but not for all altcoins for some famous altcoins itself. for example bitcoin price was 6000$ before 1 year now it is cross 18000$ and again reduced now to 9000$. due to this action altcoin have bright feature. not only bitcoin ethereu, bitcoin cash, ripple so many are there.
