Sometimes I think of abandoning my formal work and joining the virtual world to achieve my destiny.
Never think to quit from your formal work. Believe me, you will regret it!
You don't always get money from doing bounties. Many turned to be scams or failed projects, while others just ended with cents for the payment.
So, you should consider that there is no guarantee for a regular income.
Can I make $ 100,000 a year?
It is all about what you do and how good the projects you follow/join.
$100,000 is not impossible to earn. However, there is no guarantee at all.
You can earn higher or too low [far from expectation].
Note : It is better to make the bounty work as a side job.
