I was finding some information on passive income from cryptos and here is outcomes of my research.
Long story short, HODLing Bitcoin in your own wallet (not on exchange) is pretty neat option if you want passive income as well as good return over years. You can also stake PoS coins (interest rate is around 5-15% p.a.).
Longer version
By HODLing BTC you can get free:
- Byteball coins (every full moon, you’ll get free bytes and blackbytes for all the Bitcoins over which you can prove ownership – fractions can count as well). You can check full moon calendar here http://www.moongiant.com/Full_Moon_New_Moon_Calendar.php
- Stellar Lumens
- Clams (must have your wallet created prior to the 12th of May 2014 )
- BitCores (done at the snapshot from 2017-04-26 - https://blockchain.info/block-height/463604) See their pages https://bitcore.cc/
You can expect more new coins do same thing also in future (taking snapshot of Bitcoin from given time and give free tokens for BTC holder).
Same thing was happening also for Ethereum holders - OMG done its airdrop at this block (https://etherscan.io/block/3988888) July 7th 2017. If you had >0.1 ETH, you obtained some OMG dust for free.

Another way of passive income is Staking coins
Very well written article from Jon Crasy on Medium recommends few:
- SingularDTV's SNGLS
- Decred
- Ark
- Neo (for staking NEO, you don't need to have your wallet open, so it is most energy saving option)
- and 2 other tips how to get BTC dust.

You can also get interest by staking SteemDollars, and if you have something to say, you can get paid by readers by having Steem transformed to SteamPower. You can use few automated bots to upvote for you so you can get passive income from curation on Steemit without really doing much for it. It is much better if you found good articles by yourself (also rewards will be bigger), but you will need to put your time into that (so it is not that much passive anymore).
Other "bigger coins" for staking:
- BitShares
- PIVX
- STRATIS
- Reddcoin
- NXT
- Waves
