I wouldn't suggest doing faucets for the time that they have nothing to do. I would suggest that they either relax or learn something new. They have to learn another skill. To be honest, faucets are just for those people who have no skills to offer. If you are knowledgeable about something, you surely wouldn't do faucets for various reasons such as (a.) Faucets pay so little. (b.) Faucets are boring. (c.) If you can offer a skill online, you can surely get paid much more than you can earn from faucets.
You might think that you're wasting your time if you're trying to learn something new but the truth is, you aren't. At first you might feel that you have no idea what you're doing and it's lame or stupid but after a month of practicing, you'll start to feel the improvement of your skill. If you think you're good enough, go online and offer your skills to people.
for "wasting time" for me faucet is better than game. or solving captcha is good too.
but for sidejob, i prefered to learning other way, maybe like building website, building adsens, it's better than faucet.
Yep. Faucets are absolutely waste of time. You would only earn really little money in faucets and solving captchas, and you would also learn nothing from that. Your skills wouldn't be developed even a little bit. Faucets wouldn't even have an effect of shortening the process of you earning 1 BTC in a year.
