I'm currently mining solaris (XLR) (Xevan + Masternode) or Vertcoin (VTC) (Asic resistance) or ZenCash (ZEN) (privacy coin). They are not top 50 coins.
I do this with 3x 1070GTX. I do not watch efficiency too much,
It is for holding long term and I'm not selling anything(try to buy some as well) Reason is I believe these coins have potential to grow and are "ethical"". (VTC is top dog when it comes to being ethical ). It is also nice to read up on the different forums of these coins, because you have a "connection" with a coin. If you have more interest in day to day mining and dumping it is better stick to whattomine has to say.
good luck finding your own willy wonka mining ticket!
I was reading this post and wanted to know which miner you are using and are there any good tutorials on mining these. I like to have varied coins through mining
