Well, Jeff Bezos is indeed the most popular richest person, yet only because he's popular and well known for being the CEO of Amazon. But the question "who is the richest person" should never mention a family, only a person alone, and the aforementioned question is one of the uncertain and unanswerable question as some prefer to be wealthy without others being known for some reasons such as they are part of some sort of secret organization, or had wealth due to illegal businesses and transactions, and/or Bitcoin and cryptocurrencies. We will never know.
