Of course yes here in the forum you can earn without investment  rank up first and join campaign signature,avatar,and Twitter campaign they pay weekly or depends where the campaign you join and you can earn also if you had skills.

Joining signature campaign takes some time since your account is still newbie. So I think what you can do for now is to visit the Services section here in the forum and get BTC by doing some tasks or visit Games and rounds section and search for some giveaways. I think that would help you Good luck!
