You could also try good faucets like

Or simply by Mining
Please do not post any referrals links on this forum, thank you.
But faucets do provide a good way for someone to start on bitcoin. However, it's not a sustainable method as you can only earn so much at one time. Mining is also not worthwhile, unless you have a big rig.
If you have a high rank account try to join a signature campaign and also try to gain some more bitcoin on different faucet sites and invest your profit from signature campaign and faucet on a trading site and start to buy some altcoins because in trading there is a high possibility to double or triple the amount of bitcoin do you have in just a couple of days.
Well yes, signature campaigns could be very profitable for someone who is starting out on bitcoin and has a bit of spare time that he would like to convert into some spare cash that he can use instead. However, it should not be viewed as a job.
Trading is very risky, and should not be considered as a good guaranteed job either. But yes, they are some ways that you can collect BTC.
