These faucets allow you to claim every 5 minutes, and if you don't claim, the pot simply increases until you do. they offer 5 different bonuses that multiply your claims. They are:
1) Loyalty bonus: for every day you claim it adds 1% after 100 days your claims are increased 100%
2) Referral Bonus: for every referral it adds 1%, after 100 referrals your claims are increased by 100% in addition to 50% of your reference's claims
3) Offer bonus: completing surveys and such also increases your claims by varying percentages
4) Mining bonus ( you can mine straight from your browser.) This increases you claim by 1% to 100% in addition to the mining proceeds
5) Mystery bonus: randomly increase your claims by anywhere from 1& to 100%
So, if you do the math, after a 500% claim increase + mining proceeds + survey proceeds + referral proceeds x 4 different currencies = a whole lot of Bitcoin. You can then convert the currency returns into whichever currency you like best, free of fees through CoinPot (the wallet that these faucets are connected to) and then withdraw to your own wallets free of charge again.
In conclusion, if done right this is a great way to make free Bitcoin, Litecoin, Dash or Doge which will only be worth more in the future, so even small gains now have the potential to be worth life changing amounts of money in the future. I've made over a $1000 worth of BTC already just by solving the captchas while I'm watching the markets. Try 'em out and let me know how it works for you!
