Decided to write a simple guide on how to get some free BTC for noobs:

Free BTC

Faucets
Giveaways
Sig campaign
mining
Gambling offers
trading


Before everything else you need to have an exchange account in order to send the collected coins and trade them for BTC; my advice is for you to open a Crytsy or Bleutrade account. (these exchanges allow low volume trade)

Faucets
try to find altcoin faucets: http://www.dogefaucet.com, multifaucet.tk, http://www.free-crypto.com/ etc,...
send all the coins you can get to the same account and trade them for BTC

Giveaways
Check for altcoin and BTC giveaways on the forum and other forums such as cryptocointalk.com

Sig campaign
Search for signature campaigns on this forum and enroll them:

Mining
mine some coins at minergate.com, you can mine with any computer. mine BCN, or XMR

Gambling offers
Go to the gambling section of the forum and search for all the gambling sites that offer free bets. register an account and take the free bets. search for tippers on this forum and use their tips to position your freebets. Double u'r cash and send it to the exchange.

Trading
This is a risky option that can easily make you lose all your BTC but it can also give some good winnings.
my advice is, as soon as you put together a good ammount you can use Hashnest to mine BTC and trade GHS at the same time.
