Running your own NextCloud, Jellyfin, Home Assistant, Bitcoin, Lightning and other services. On your own hardware in your own home - not on someone else's server, but on stuff you have the most control over.

Ok, I used to do that in the business I used to run. It is a lot of electricity and work. Today it is for me not possible, due to no home. I live nomadic or as a wanderer.... Or however you want to call it. So, to have my own Server is a little problem.
Thanks for explaining.
