How many billionaires with a net worth over 100 million US dollars are there in the world? Do these billionaires have their own circles? Of course they do! They are the four billionaire clubs that can be counted on one hand globally. There is the mysterious "private sea" opened by Greek ship kings, which lets you know what true nobility is. Billions of dollars of stars are not qualified to join; There is the "Billionaire Club" created by Italian playboys, which is extremely luxurious, with beautiful cars and women, fine wine and food, and dazzling wealth; There is M1NT, which includes 44 billionaires and many political figures, allowing members to enjoy the fun of making money while spending millions of dollars. But these clubs have a common characteristic, which is extremely strong privacy. There will absolutely be no journalists.
