Bounties NEVER made any sense
Dressrosa
Luffy defeats Doflamingo, received 200 mln
Zoro defeated Pica and clashed with Fujitora, received 200 mln
Is Pica = Doflamingo?
Obviously not
It's just that bounties are given very casually
No much thought behind
Wano
Luffy defeats Kaido in 1 vs 1, received 1,5 bln*
Law and Kidd defeat Big Mom in 2 vs 1, received 2,5 bln
* he received 1 bln for defeating Cracker, drawing with Katakuri and running away from WCI...
Nothing of this make any sense
