Good luck with that, it may have been possible years ago, but no longer. Most faucets offer very limited rewards, for example, there's moon litecoin, which pays in litoshis ( 0.00000001 ltc ) , and pays out once you reach 500 of them in a week, so as you can imagine, it takes a very very long time. As for BTC faucets, it's usually quite less. Your best bet would be to use all the referral bonusses from several faucets, and use rotators like crazy to use all faucets every time they are available.

That is alot of work for the little you get in return, if you have a job, it's better to just buy a bit every week and watch the markets to profit from trading.

Good luck @parkus101 ! :)
