Yamato in the room.... Fake.
Marco having 2B... 2B mark is when you are a solid top tier, you won't be losing low low diff and quit piracy.
Not saying spoilers are real but we honestly know nothing about what he's done before the story began so can we really make this assumption? He was Whitebeards number 2, tbh, him having a 2 billion bounty isn't even surprising
Bring WB number 2 means nothing
Marco has done nothing to merit 2 B.
He isn't even a conqueror.
Base Teach has done more than Marco has ever done.
Teach was fighting shanks while Marco was just a doctor who can fight
Teach beat Ace, who did Marco even beat at MF?
Teach beat Marco low low diff... There is no way someone with 2 B loses in such shameful way and quits.
Teach got WB territories and acquiring dfs
Yet his bounty is 2.247 B.
Teach would have been in 3 B Mark if Marco bounty was 2.1
Beating Marco alone would give him 2.1 B, now add the other factors.
The safe bet is Marco has 1B+ bounty, you .. And all the factors behind, The other 1 B increase.
Teach's 2.247 B :
1-1.5 B for beating Marco and Ace, killing WB, fighting Sengoku and Garp
500M - 1 B for dfs, freeing Prisoners, territories and allies.
Like Luffy 1 B increase :
500M for beating Kata and Cracker
500 M for being Sabo's Bro, having Fleets, influencing germa and being the "mastermind" behind assassination plot against BM
