Good post! You can also get coins by staking (Im saying thats different to mining) as you dont need special hardware, just put your coins in to a core wallet and 'unlock for staking' and see the coins roll in.
Another option to hash/scrypt mining is researching, Gridcoin uses that, you dedicate your ordinary computer to researching disease cures and you get crypto for it.
Another thing you can do is loan out your spare computer hard drive space, coins like Sia pay you for that.
Even more fun is SolarCoin where you get paid for having solar panels, every 1MWh you make = 1SLR.

Crypto sure is an amazing place, so many cool ways to earn some.
