Mining Rig from Scrap?

Here is something else that might be worth looking into. Apparently you can sell your excess computing power to some places.

Edit: Looks like solidify is dead. I heard about it some years back, but didn't know it had died. Maybe some of distributed computing options still work. At least the other sites mention in the article seem to still be up (DigitalGeneration, MQL5 Cloud network, Peer Zone). I've never tried it before so I'm not sure how well any of these places actually work.

1. Slicify

Using software created by companies like Slicify, you are able to set up a partitioned Linux Virtual Machine on your home PC. This means that other people can run software on your computer, without having access to any of your personal information, programs or files. It is essentially a small-scale version of what large companies like Amazon or are doing when they rent out their servers to other businesses. It is known as Distributed Computing.

How do I get paid?

Currently, Slicify uses PayPal to conduct payouts, so you will need to simply set up an account to get paid.

Whenever your machine is rented, you are paid by the hour.

If you make referrals to other people, you can also make referral bonuses from the work done on their computers.

How much will I make?

Larger companies using this process currently charge between $0.02 to $4.60 per hour depending on the need and capacity of the PC.



For home computers, you can earn between $0.10 and $0.40 per hour, depending on the provider and service.

You have a chance of making more on Slicify because bidders can compete for your PC.
