In my honest opinion I do not think this is possible. Because many people are investing in bitcoin so as bitcoin value depends in supply and demand so if the banksters and governments hold 90% of the supply the value will increase making a lot of people very rich.
I still believe top 1000 people are holding 92% of Bitcoin.People are sacred to Bitcoin after it's fall from $ 17k, so average earners will never risk buying a Bitcoin even if you hype it will rise 1000% in a year.
