Bitcoin is created for all groups, races, religions and all humans, only rich people can use bitcoin because they have money to invest or buy in large quantities, That's just the difference between rich and poor in the Bitcoin market, rich can buy in large quantities and poor can buy in small amounts.

Considering the current price of Bitcoin is high and expensive, of course the rich are free to do anything, actually for the poor there are already opportunities to be rich in 2009-2016 when the price of bitcoin is still affordable for the lower classes, There is no regret at this time, everything has an opportunity to determine yourself in Bitcoin.
