I have been earning BTC through different claiming faucets like BTC clicks, Freebitcoin, Bonus bitcoin, adBTC, Moonbitcoin, Fieldbitcoins with no referrals for about 4 months now. It is so hard. Can someone tell me how can I earn more?? 
Why do not you think of working hard to increase your current rank to a member or higher. You can become a bounty hunter and you can earn more bitcoin than faucets. Having with faucet is not just a waste of time because it is still a way of earning btc, but it takes more time and days to earned btc. Having a ways stated above, it takes time also but not as far as faucet can do.
