If you are looking at Alt coins for long term investment, I would recommend to read on Library credits - strong development team and great road map.
LBRY protocol is expected to replace services like Youtube, Spotify, iStockphoto and Amazon Kindle in long term.
The LBRY App is now in its closed beta stage, and will be released as open beta soon.
You may use the below referral link to get the invite.

@clickvicky I that as time goes on, you will see the whole education/e-learning/self-published expert space move to this platform. I am excited to see what it has not only for investment potential, but how it can improve the quality of content being put into that LBRY ecosystem. Not exactly Bitcoin, but much more robust than your average niche altcoin (not unlime Steem/Steemit!).
