This is my method in earning bitcoin. I go for forum site and faucet site for earning capital funds. Then invest my bitcoin to online investment site. Other option is trade my bitcoin in trading site. Buy for stacks and sell it as price is up. And last option is gambling I try my luck to bet to grow my bitcoins.
By faucet sites, you mean one of those paid to click, watch,visit site, etc? hmm. I don't really have any ideas about those, never bothered to try. But I am familiar with the ones on casinos,where you can play with it and possibly win thru gambling.
Then for earning, Signature campaigns are easy but can't really depend on earning much. Offering a service or working for a site with Bitcoin as payment is good, then there is investing. After that is the occasional win on gambling.
