There might be many more rich persons in the world other than these but it depends upon whom you call a rich person. For me having only money, dollars, gold or bitcoins does not make a person rich. For me a person is rich if he is healthy, do not have major problems and sufficient source of income to run his life.
Agree with you. Money is not everything in this world.
You can be as rich as you want, but you can not buy true friends/family with it.
Thats is what makes people rich in my eyes.
