**Update: 2022-04-09**

We've published updated scripts on our Gitlab server:

- [Guix on DigitalOcean](https://git.pantherx.org/development/applications/px-install/-/blob/master/guix-on-digitalocean.sh)
- [Guix on Hetzner Cloud](https://git.pantherx.org/development/applications/px-install/-/blob/master/pantherx-on-hetzner-cloud.sh)

These support both Ubuntu 21.04 and Debian 11, and usually finish the job within 5-10 minutes.

> What is Dual-Mining? What is considered baseline, the AWS instance cost? - D.

DUAL stands for dual-mining. That means, that you are concurrently mining 2 or more currencies. For example, you could be mining Ethereum (ETH) and Siacoin (SC) together, thus making a higher profit compared to only mining Ethereum. The baseline is ETH + SIA, so mining only ETH would generate around 27% less profit.
