Bitcoin have future thats for sure. I do believe that there will be some alts standing still not just LTC and ETH but these as well: DASH, DOGE, XMR, ZCASH
There will be more of them. But the point is and will stay prob most of the alts will exist in the future for the people to gamble upon, to create fake value. We all know that most of them were made for profit and nothing else.
Yes!! I Think so altcions have a future. as a result they we can get ahead in life. Hopefully not lose it in the meantime as a result they expect us to lift up the life. Hopefully not lost the internet, cellphone for consistency the altcion would learn also it most to all of us grow
