I will feel miserable if this happens. $50 is just too low for 8 weeks work. However, you really can't complain about it because of bounties are transparent on token allocation and they cannot guarantee the coin price. Also, your rank is too low for signature campaign. Jr.Member's will get the lowest stake per week and its much better if you increase your rank first so you can get more.
Increase in a rank does not guarantee receiving good payment. It is more and more participants, pools are one company more lesser. The projects paying promised too.
