I think it would take years before you could earn 1BTC using faucets. Solving captcha takes a lot of time and effort and it is so very hard to earn 1 BTC by using faucet only.
I completely agree with you on the cranes and other passive ways to earn. But while I want to say that for this work does not need to make a lot of effort, so all the coins accumulate automatically. Although I believe that communication needs to waste time in vain, and find more or less the best ways to earn Bitcoin. It is better to pay attention to the signature of the company and that will be more.
