Many people still choose captcha and faucet. But in my opinion both spend a lot of time and energy with results that are not so satisfactory. For me trading and playing signature campaign into a very seductive option. Because by concentrating on it then we can get many benefits.
Yes signature campaign and trading will give you better results in compare to captchas and faucets but its good for newbies who don't have any idea of earning bitcoins in other ways as it can boost up their journey in bitcoins and at least they can have some amount of bitcoins in their wallet and in future they can learn other methods of earning bitcoins.
