Are you talking about a service? If you have any kind of trust you could look into setting up a website which automates the process of paying cellphone bills online. The only thing is why would anyone trust you?
True, I think of alot of things sometimes, sometimes i don't fully think before i type,lol
I also thought about a skill based block game via btc/other crypto's - then again, would cost to much to do
Thought about selling shirts - Doubt any interest here.
blah blah blah
