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.
It appears that the person who introduced the OP didn't provide adequate guidance on how the forum works. In reality, there are various ways to earn within the forum, but it's not an immediate process. When you read the rules in the 'Read Before Posting' section, you will find guidelines that outline the requirements and expectations.
Before you can start earning,
you need to contribute to the forum and serve the community. This means that earning is not a instantaneous process, but rather a result of active participation and engagement within the forum.
