I don't know if I can suggest any, but I can tell you that I hold some Litecoin, Bitcoin, and some Peerplays that I bought at $5.00 during their latest ICO. Other than those and STEEM, I only do some trading with different cryptocurrencies.
Maybe I can get @wingz can help you with that - or check out his latest blogs. You can also find some good information from @razvanelulmarin.
