why don't we just set things up and do like what jaredfromsubway.eth do?

let's start with the first question:

what does it take to be jaredfromsubway.eth?

how many starting e is required?

hardware?

software?

for techical side i think it's not that hard to set it all up, many eth devs can do it

i don't know if, you know what im asking right

like, if doing so makes so much money, why don't everyone just do it? what's the barrier on this? (if there is)
