yeah that bit of context could explain why it might be high for buggy but tbh I really think he is an emperor despite not having the highest bounty lmao
note none of the the providers have really hyped up buggy's reward instead commenting on mihawk's
Thing is, I dont see a problem either way honestly.
Because Law/Zoro confirmed in the Cross Guild introduction chapter that Buggy's hype is due to Mihawk & Crocodile.
If Buggy has a lesser bounty than them, its explicit confirmation.
If Buggy has more, then it's only natural since he's the one being prepped up as the chairman/leader of the guild.
The most that anyone can use to taint this Bounty for Mihawk is by saying that he is now hunting Marines for money so the Marines kinda bumped his bounty. And that doesn't really make sense if not for Mihawk being that strong in the first place.
