I am a newbie to bitcoins. Can anyone tell me what are the ways that i can earn some bitcoins without investment. I am currently using faucets,PTC's and earned around 5,000 satoshis in a month. It's really low, I know. But can i earn roughly 1BTC in a year without investment and only investing time. Since I am a newbie in bitcointalk, after a month or so only I can become a jr.member and go to sig campains. Can anyone suggest me some ideas?
