I don't generating bitcoins, I earn it. I never tried to mine bitcoins, because it requires big investments and in mostly cases it's not profitable. I earning bitcoins from these sources:
I'm still using faucets. Earnings are low, but it's better than nothing. I'm also earning commission from referrals
As mostly on bitcointalk, I earn bitcoins from signature campaign. Forme it's fun and easy way to get bitcoins. What can be better, than get money for doing what you like to do.
Sports betting. I'm not betting very serious. I only betting on my favourite leagues and teams.
Trading. I don't get big income from trading, because I don't have good knowledge. Mostly I'm trading bitcoins and few popular altcoins.
Sometimes I'm participating in new altcoins giveaways or contests. But mostly getting only small amounts.
Bitcoin is my hobby, I'm not looking into it like to money making machine, but it's fun to get money from what I like to do.
