I don't really see a point of those type of people trying to use Bitcoin to purchase whatever they want since they're already rich. Bitcoin does not have any weight to it when showing somebody the amount of coins they would have, if they show how many paper money that they have then people will get jealous and is more than likely to be controlled by the holder.
I agree. They have sufficient amount to spend to satisfy their needs. What's the point of getting bitcoins if they have much money which much more convenient to use for daily transactions? Another thing is why they have to risks their profit if they can obtain that in their own jobs or businesses with assurance. Besides the risks, These type of people have no time to spare, i think they can't afford to lose time in this kind of business
I think not all bitcoin holders are rich, some are very dependent on bitcoin to meet their daily needs and maybe they only earn from bitcoin and have no other business at all
