no i think.
rich family or people wont use bitcoin. because they have a lot of money. and i think cryptocurrent use for people that need money

like me

but if it happen, it will make me more rich. because we can earn bitcoin from this forum or other way, but they will be buyer, will consume what we get.
It seems to me absolutely wrong the idea that bitcoin is only for people with economic needs and not for rich people. But this type of mentality is usual among those who join this forum trying to grasp all the free money they can with the least effort.
But of course bitcoin can be used by all social strata, and in fact its adoption by famous and rich people would be adequate to give it more visualization in the media. But it is difficult for this to happen due to the legal restrictions that still exist against bitcoin, and these famous people would hardly take the risk of getting involved in problems with the authorities just for supporting bitcoin.
