I suppose the fastest way without regard to the amount earned would be faucets. There are hundreds, if not thousands out there, but I have not found one that is worth the time.
If you are in to faucets sir, i highly recommend moonbitcoin and freebitcoin. Moonbitcoin gives you daily reward so the more you use it the higher the daily rewards will be while freebitco.in gives you reward points per claim which you can exchange for gadgets, etc.
Yeah , for now freebitco.in gives you reward points and you can exchange it with gadgets.
For newbie is good to use faucet for know how bitcoin's works and at least you know the features about bitcoin , but after that you can try different method which more better than faucet out there (including this forum where you can earn lot of bitcoin)
