Hi, I was wondering if I should quit my job and focus more on bitcoins? Because I think it might get me even richer without a job? 
No you shouldn't, you can still earn bitcoin while having a job. It's good to have a stable income, because if you will just focus joining campaigns, it will take a month before you can earn your money. You don't need to devote your whole time posting, you can do it 2 to 3 hours every day and still earn extra money.
