Daily Bitcoins: This is the only faucet I’ll mention just because it is that good. It pays 10uBTC every hour. If you have the time and you spend a lot of your time online, you might as well use it every hour. Note that there are also several bonus payouts, with as high as 1000uBTC payments (rare) but several 50uBTC payouts. You’ll find these under Prizes tab on the top. You’ll also get several vouchers for PeerBet and coupons for advertising on that site as bonus.
