Im not sure if i know exzactly hat the main posts problem is but i have noticed faucets that do not pay out (would this be a ponzi?) I have found a few good faucets for android that i can recommend if the original poster would find it usefull. If i am completely off the mark here apologise i am trying to learn more about bitcoin.
If those faucets are not paying than we can call them SCAM and all HYIP (high profit sharing programs) can be called ponzi because they use new investors money to pay older investors.
Defination of PONZI
https://en.wikipedia.org/wiki/Ponzi_schemeA Ponzi scheme (/ˈpɒn.zi/; also a Ponzi game)[1] is a fraudulent investment operation where the operator, an individual or organization, pays returns to its investors from new capital paid to the operators by new investors, rather than from profit earned through legitimate sources.
