in other words your aim is to find someone else's money and steal it from them! so you want to be a thief.
My thought exactly. It's extremely unlikely to have this ever work out in a 'profitable' manner, but the intent is what matters here, and that's pretty much to commit theft. Not particularly a great entrance for a newbie.
OP is better off trying to find a non illegal way to make money. It could be that OP doesn't consider it to be theft, but come on, how obvious does it need to be that loaded keys belong to people. Bitcoins don't grow on trees....
It's called a collision. Even if you have a considerable resource to try it, you would be better off to put all the resource to mine Bitcoin directly.
Or just stop being lazy and put some effort into skill development so he doesn't need to resort to things that are heavily frowned upon. Investing in Bitcoin is even more profitable than mining it and it's noob friendly.
