If you install Fedora minimal via the Net Everything installer, then install only the desktop environment you require (lxqte, gnome, etc), it'll reduce the amount of updates and overall surface area drastically.

My #Bitcoin Machine only has ~1500 RPMs installed and runs at 5% CPU and <500mb memory.

I run ` dnf update --security --bugfix` often but only `dnf update` maybe once every other month.
