I heard from someone that if you want to earn money without any investment then you should go to bitcointalk. But he also told me to keep alert. I created an account. I am feeling very confused but I am not able to understand anything.
Couple of things you can do:
1) sell goods and services to other people in echange for crypto
2) join altcoin bounties and if you're lucky, get something worth a few $
3) join signature campaigns and earn better, but you have to rank up and start posting quality content
