Lisk, Litecoin, Library Credits, Siacoin, SysCoin, XEM, Stratis, PIVX, Reddcoin, Dogecoin, DigiByte, Bytecoin, Stellar, Ark, Golem, BAT, STEEM (of course), and a few others. Some I'm holding long-term, others I'll unload the second the price is right. I don't want to trade regularly, so I'm looking to reduce the number of coins I hold and focus only on those that have long-term growth potential.
