Faucet is profitable because it's free. Pretty simple. No risk at all, and you get free satoshi, free reward points, and free lottery tickets that could even give you a chance to win more. I remember some guy won big from only 2 free lotteries (given from a freeroll).
Also not mentioned is the interest you earn automatically every day for balances of 30k satoshi or more. You don't have to do anything, just keep money there and you get interest every day.

So you think your response to that user is profitable in a wise way because of that "no risk" and "free"?
That user is not asking on about ways but how those ways became profitable.
Don't say to other people that they are not learning much if you will respond YES to my question.
