Mine, in no particular order:
Bitcoin - has the most invested in it and the most mature infrastructure surrounding it so far. network effect
Litecoin - like Bitcoin, but with no risk of 'toshi dumping the price down from 10,000 to 10 dollars
Peercoin - more energy conservative, DACs like Nu use it to pay dividends, it's the oldest cryptocurrency that isn't just a clone (Namecoin excepted)
Primecoin - can't understand why PoW chains don't embrace energy multi-use more
NXT - it's just an interesting project. basically bitshares but built differently and lacking MPAs. can't wait to see where it goes
NuShares - originally I perceived nu as less socialized and bitshares as more so, that's why I brought my enthusiasm here. those roles seem to have gotten switched at some point so I have a renewed interest in the Nu project now.
Blockshares - read the whitepaper if you haven't. it will blow you away.
Ethereum - Grabbed some just in case. seems to be a lot of hype that could result in network effect.
BTS, MUSE, and PLAY, Obits, METAFEES, UIAs, and if the option becomes available and I decide to bite the bullet STEALTH, and any other FBAs I might begrudgingly decide to (re)buy into - my interest in these is pretty obvious
Monero - all their shills talked me into it. it seems like the best stealth option available right now, i guess it has some bitcoin core devs working on it? i think the market cap will go up once there's some good GUI options out there, and americanpegasus is a helluva writer.
QORA - I had some but I think I deleted my wallet. I backed up what I thought were the files that made up my qora wallet, but with this new version I'm completely confused about how to import them. the price nosedived anyway and I didn't have that much so I'm not freaking out about it... yet
What's your HODL list, and why? I'm not talking short term speculation, I mean what coins have you bought with the intention of hanging onto them?
