My girlfriend got $1700 from Facebook Bounty only because the project was hyped and successful. Only 2 weeks they reached the hard cap and the bounty was then sent within few days after the ICO finished and the token was listed right away on exchanges. So it all depends on the success of the ICO and if they are already listed on exchanges
Your GF is lucky only 2 weeks they reached hard cap means it is unbelievable, that is why people tell bounties are like a onetime jackpot. Even I also participated in one bounty but when I joined only 3 weeks left to close that bounty. after that I received tokens and the value of token went up to $2.50 made approximately $900. but sometimes we will not get anything that time it will hurt but can't do anything.
