https://storj.io/share.html (earn by sharing unused space)
This is one of those things i think is great, bringing some possibilities for income to those who may not be able to work outside, even if its a small amount of money, maybe it can become more in the future who knows, im sharing three HDDs at the moment, have gotten paid, and it is still developing, now we just need some more people to rent some of the space we share.
If you keep 1GB for a whole month, you earn minimum payout. (used space * hours) * days, depending on the days per month its usually around 700 GB Hours. you can store on different HDDs and it will be calculated together, payment is made in STORJ coin.
here is a link for those who need some extra space for maybe photos, videos or maybe just large amounts of text, the choice is yours: https://storj.io/index.html
