I made a lengthy post here - https://steemit.com/finance/@irishfan686/my-power-5-long-term-cryptocurrency-investments discussing my top 5 altcoins at the moment. I touch on their purpose and their recent price history.

To sum it up - Stratis, Ubiq, Waves, Golem, and Ethereum. Good luck and trust in the process! There will be ups and downs, but blockchain will have a major impact on the future.
