Compares to other activities in a trip stepping outside of the core, bounty requires a bigger fighting fleet that eat up supply and fuel fast, especially hyperspace stormed, than making planet survey(surveying ship cutting supply cost), derelict location(salvage ship for bonus) and sensor packaging(no cost at all).
Risk for bounty is losing some ship, can turn into logistic disaster when crew and supply are drying out, or capacity loss, and/or ending up costing sp inorder to save sp invested earlier. Potentially taking longer time to look for as many dwarf and barren worlds are presented in the same region. Similar risk of getting lost also presents in exploration, but still within a designated system, and giving up cost a little relation, looking for a ship in foggy system's vast asteroid ring far away is peak pain.
Reward for bounty, beside money, is to farm relation supply xp sp, ships and weapons outside of typical market, the ideal snowballing gameplay in mnb type of game, restricted by how much one can chew, and it still cost sp for good ones because free salvage is taken up mostly by trash. However, similarly gain can be done by farming redacted for weapon, and ship if skill permitts, while exploration gives unique items and blueprints, sensorpackage on a ship at rare chance may lead you to some high end yet well preserved ship, multiple if its in a battle field at chance, and high lv officers at chance.
Ultimately money conveting to supply or gains is still inefficient and restricted.
The need for traveling with giant combat fleet is less consider sp allows small fleet to get out of jail free with sp manuver, while bigger fleet attempting escape harassment cost a huge amount of cr, thus a dent in supply, or out right can not get away.
