I have been doing a lot of bounties yet I have not received a jackpot reward but that will not make me stop doing bounties. If we stop we will surely get nothing but if we continue there is a chance that we can get something.
I like the spirit, its not over until it's over, that you haven't hit the jackpot doesn't mean that you wont, just strive harder and be persistent and committed and you will surely meet that project that will fulfil your wish
