If I had to guess the method I'd bet it has something to do with a faucet of some kind. Why would you need 30 minutes per day and it's "not appreciated"? I bet the "secret" method can be switched off at some point and then the "secret" becomes worthless.
I'll pay him what he requests only if he gives me the secret upfront and after I earn the defined amount. I was thinking of a faucet too. It might be gambling as well.
