I know Jeff Bezos is considered the richest known person but there is a lot of hidden wealth in the world.
I've heard the following people may actually be trillionaires:
Putin
Oil Saudis
Rothschild family
I dont care what people might say about the Rothschild, Putin and the rest of them that you all have mentioned here, but since they dont want to show what they have, then Im sorry to say they shouldnt be regarded to as the worlds richest. Only those that have proven to be that should be on the list. So as long as Im concerned the world richest man is Jeff Bezos, followed by Bill Gates and Warren Buffet.
