I don't think I can earn much BTC from crypto forums. I focus on my outside work to earn extra income and use a portion of that income to DCA BTC + ALTS. This way is more efficient and generates more BTC than signature campaigns.
Like what @bitmover said, you're very much welcome to join in the Bitcointalk forum, and possibly earn more BTC there (if you reached the minimum rank required.
Well, it will depend on the income that you are earning in your day-to-day job, and the free time that you have. I spend at least 4 hours in both forums, and the other time are being used for myself (playing games, exercising through jumping ropes, helping the home etc.). I guess it will depend on the time you have, but if you have extra time to contribute in Bitcointalk, many would appreciate it for sure.
More income = more money to invest into crypto and other assets = more happiness for sure.
