Do not waste your time with them - you will not get paid; the site is a scam.
After reaching the minimum withdrawal amount (100,000 satoshi / litoshi / dogecoin) and requesting payout, we have gotten an error code page showing the withdrawn amount has gone into the air. The amounts of satoshi / litoshi / dogecoin have vanished from the account.
After about ten days, we have made another test for Rocket Bitcoin faucet. Same result!
Two weeks ago, we have contacted the owner - using the email from whois.com because on the site there is no contact - and we have gotten no answer.
Meanwhile, the Rocket site develops - this including more advertising, too.
The owner gets money from advertising and doesn't pay the members.
Rocket BTC / LTC / DOGE = A scam from day #1.
