I think you have to seat down first and think if it is possible for you to achieve that and thinking I am talking of calculate on how much you can earn that will be able to help you and taking care of your daily needs. Bounty can replace your daily job if you are ready to work hard in study those projects that you may think will help and give good income.
Sitting down first and thinking it through is very necessary to avoid regrets and stressful living in the long run. I think answering the following questions honesty would be a good pointer to what decision to make:
1. how many bounties have you participated in so far;
2. how much did you make from the bounties;
3. how much of what you earned was spent on your basic needs;
4. how much balance do you have presently;
5. can you survive with that balance for say 3 months in case the next payment takes that much time to come;
6. how sure are you that you would find 100 bounties per week;
7. how many hours are you online a day?
My advice is that unless you've set aside a huge savings and already have a tested and working option B, don't quit you job yet, because a bird at hand is usually worth two in the bus.
