As a student I collect a bit of satoshis from:

http://cointiply.com/r/7R9lK -> around 200.000 satoshis a month (faucet, PTC, Offerwall and games).

https://bitnyx.com/?r=41128 -> around 50.000 satoshis a month (faucet only)

https://ref.adbtc.top/1012017 -> around 50.000-60.000 satoshis a month (PTC)

https://www.weheartbitcoin.com/?id=27131 -> around 50.000 satoshis a month (faucet and PTC)

https://get.cryptobrowser.site/1833319 -> around 5000 satoshis a month (passive mining browser)

But I also get refs to boost my income. Its not something you can live on. But if you are a student or have a part time job and want to earn a bit extra on the side line, then I can recommed it. It has saved me a time or two at the end of the month, if I have spend a bit over my limit.

I also use some smaller income sites to advertise for refs. It helps a bit too.

But good luck to you in the world of crypto
