Ha! How I wish I could I neither have the tech expertise nor the money to have a server
It's why Youtube was invented mate, as for the money, you can start small and use second hand kit to get it up and running. Not all our esteemed witnesses are using 10k servers ;-)
I saw a witness guide one time and that to run at the needed 64 server specifications it costs about 400-600 USD not to mention if you are not in the top 20 you only get to be the rotating witness.
We will see in a couple more years hahha. I do see myself doing this long term.
