in my opinion i will choose ethereum, zcash, and litecoin
zcash is already half dead and ethereum is a zombie being pumped. the only remaining option is litecoin and not because it is a good coin but only because it belongs to Chinese and they love it.
and you are forgetting about coins with something to offer like monero and iconomi
Sadly I think this is true, though I've been biased to ethereum I think litecoin might really be coming up the stage but I hope ethereum would last longer and gain more value before the year 2018 ends or just until I earn profits through my investments. I don't want ending up cutting losses from my resources.
