That's the case for bitcoin, litecoin, etc... whose only added value is anonymity which is -let's face it- not something important for everyday customers. Only crucial for dark economy like drug/gun trade.

There are real value-adding coins out there, which utilise blockchain technology to actually generate value. Like Steem which is powered by its users or JSEcoin that allows browsing without ads thanks to browser mining (amazing idea!) or SiaCoin that allows you to lend your extra storage space. I think those might be of some value in the long term. Not for daily traders but for those that put some money there and forget about it for the next 2 years.
