400,000,000

yeah I heard from numerous spoilers that it would be 400 million, even before the whitebeard arc begon, people were saying he would get 400 million ( I dont know if they were guessing at the time or not, cuz I heard someone else say at that time he would get 1 billion xD, but that is quite some time ago)

heheh , the fake luffy says so :)
