I also have question like you some months ago. Hope these words help you:

I started looking for free faucets, free mining and you can search google for them to earn a little.
However, the effect is not high, to get the little copper we have to spend a lot of time, besides there are many sites do not pay as promised.
Currently, I'm researching and doing airdrop and bounty campaigns to earn free token, when this tokens onto the exchange and raise we will have money.
My experience from the process, nothing is free. we receive rewards from our efforts and time.
So learn a lot to choose good projects to put effort and time.

And if you can save a bit for investment, it will be more effective for you.
Dear.
