Could it will be a ponzi scheme?
What do you guys think about coinpower.io?
According to a link you given its looks like it needs to register with username and password this kind of faucet has manual payment.. some of them are risky and scam and some of them are paying good.. i can suggest to you if you are looking for a faucet better to go in faucetbox its instant receive in faucet box and your reach the threash hold you can receive it in your wallet..
But for me claiming in faucet are wasting time for now..
