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.
That's a really stupid reason for continuing.
Can you imagine a gambler saying: "If I stop gambling now, then I surely won't win a jackpot"
It's the same here, only you're gambling with your time and getting almost nothing in return.
How much are you being paid anyway, if you honestly look at how much time you've spent.
Can't be more than a couple of dollars per hour. A minimum wage job would earn you more than that.
