Is this something where you can use the faucet to get free bitcoin and then make a decent profit out of it? Like how much using th faicet? I assume you still need to manually enter the captcha to get the bitcoins.
Well the faucet is it's own entity, you'll need to hit that before playing this portion, which is stated up in the top of the OP "Multiply Bitcoins" is where this script will run.
So yes, once you do the Faucet, I do recommend getting a good 2k worth before hitting this hard, right now I'm sitting over a free 62k waiting for tomorrow's payment after about an hour using my way above. I do adjust a couple things here and there, but works as intended.

Have you tried pushing it further than 62k or are you just doing that to be safe? I think if the script works well, and it has a decent chance of coming out ahead, it may be worth going for a BTC, :p.
