2) Why would it be deleted? It will be moved to beginners and help
We're on February 6th and it was not moved yet. I guess that it will never be. Personally I would have put it in the mining section.
#1 create vanity addresses. I currently do this and its not much. I mainly keep doing it for the fun part (as in how long will it take to actually find it).
#2 brute force wallets. If someone has forgotten a password they usually remember enough about it to brute force the wallet file. Very small market, requires to be trusted. I would do it, but for most users there are other solutions.
#3 sell CPU cycles via bitwrk[1]. No demand, might take off in the future
#4 mine alt coins? Not sure if thats still a valid way to earn. You might get infected by a virus via the alt coin wallet though.
Other than that I dont know of any ways to let the computer to the work for you. Probably forgot something.
