Bitcoin is open to whoever want to purchase it irrespective of who you are or where you are from
Accumulation of Bitcoin among the rich is fast, because they have all it takes to buy it, but for the other class, the accumulate gradually either daily, weekly or monthly whenever the resources is made available for the little the chose to buy using the DCA method to help them grow, buy at least $10 per week.
Yep, for now the difference is only in the accumulation stage because it is clear that for rich people they will have a much larger number of bitcoins compared to poor people because they have greater resources and don't bother too much with financial distribution when they want to be in bitcoin in contrast to poor people who really have to think about several things including financial management that must be more closely guarded in order to invest without any interference.
But in the end this certainly does not really affect anything because in the end for now no matter rich or poor in the end being in bitcoin is certainly an option. As long as we want to be in bitcoin then regardless of whether we are poor or rich as long as we have the intention of being in bitcoin then everything is up to each person in the end.
