It will not be very difficult to guess who can be the most ahead in this competition in the future world. I have been seeing a lot of rich people collecting bitcoin lately and there is a big competition to collect bitcoin among the recognized rich internationally. Now the day is not so far when the top several company owner all over the world will also be defeated by the BTC holder.

That day won't come anytime soon, if it ever does. The people you listed as the richest people in the world are only those who are publicly known for their wealth, and there are those who are not publicly exposed, but possess far greater wealth that was created over generations and is measured in trillions of $.
A question for you - what would the price of 1 BTC have to be for Saylor to overtake Mr. Mars on your list?
