Just to even be included in the top 10 list, the bitcoin startup would have to beat the tenth richest person in the world, - Liliane Bettencourt. Her net worth is over $40.1 billion that she earned as the non-executive director and major shareholder of L'Oreal. Just to be on the same rank as her one would. need 148,584,575.1000 Bitcoins. The maximum number of bitcoins in the world is just 21,000,000 BTC. That would mean the startup would need to own all the bitcoin in the world, and then 127,584,575.1 more. At this current value, this is impossible.
