Bellamy =/ internal organs damaged
Jinbe can attack and go beyond any normal defence, not to mention water is Cracker's weak spot.
Sure, that's why he has 2B.
Damaged internal organ was fixed by his df. Luffy said they're both damaged.

2 billion because of intelligence and leadership. Zoro bounty was lower than King despite Zoro already beat King.
