'use-modules' currently only behaves well on the top-level, I recommend
moving it into #:modules (see e.g. glibc).

This can be simplified a little by replacing (assoc-ref outputs "out")
--> #$output.

Phases don't have to return #t anymore, this can be removed.

I think ‘Monero miner’ would be more descriptive.

This notes many positive qualities of XMRig, but ignores the negative
quantities.  Perhaps you could add something about high energy
consumption?  (See recent thread ‘Excessively energy-consuming software
considered malware?’ on guix-devel (not yet on lists.gnu.org
apparently).)

(I'm assuming here the situation is the same as for Bitcoin, but
I don't actually know if this is the case.)

Looking at
<https://github.com/xmrig/xmrig/blob/master/src/App_win.cpp>, it
appears to be gpl3+.
