The best and highest paying BTC faucet [FREE BTC]
This BTC faucet gives out mad amounts of satoshi and you can claim it whenever you want. The way this works is that you can close the page and come back to it every few hours and claim it. Over time, the satoshi will build up automatically. You can leave the page closed and come back to it even after a week and you'll have thousands of satoshi, ready for you to claim. 

This is pretty much my favourite and my most recommended BTC faucet.

EDIT: Bookmark this thread or bookmark the link for easy access to the faucet. I recommend claiming it every 2 or so hours but its fine to just leave it for as long as you want. (The longer you leave it, the less satoshi. The faster you claim you can maximise profits but it can sometimes get annoying checking all the time)
