I completely agree with you. The Bitcointalk forum has an amazing affiliate program that can help us earn some extra cash. And besides, with crypto trading, we have the opportunity to make some serious money in the future.
Look, This forum is not a job, it's a forum to learn about anything related to bitcoin. You can also learn other things and offer your services for hire but the forum on its own is not a job. Nothing stops you from having a job and still being on the forum. If you see the forum as a job then you have already missed the whole point of the forum.
You can have a job and still make money from the forum through signature campaigns, Bounty, and advertising your skills (if you have any) but don't take it as a full-time job.
Like you said "extra cash". It can't be termed "extra cash" if it's your full-time job.
