ETH is the clear long term HODL.
I've played around with Golem too - trying to get out of my position currently - still for a profit, but I held too long.
I also managed to get in at BAT ICO - I shifted half my stash for a 6x on my ETH buy in, but I've held my second stash for too long and am currently trying to close it out for around 3x my ETH stack in the equivalent BTC.
ANS is an interesting one and I bought in a week or two ago, it's another potential long term HODL - as it would effectively become the ETH of China - if mass adoption kicks in, it will explode to the moon.
Crypto is so unbelievably volatile at the moment, anyone claiming to read the markets is bullshitting, it's a cluster**** of guesswork and speculation.
You're best having a few strong long term positions - I would say ETH/BTC/FCT are probably the best, potentially ANS - anything else is swing/day trading and pure luck.
It's a hell of a lot of fun though!
