Yes, not just in bitcoin investment, in life generally the rich have more advantage than the poor for so many reasons, because they are exposed to the best education and after graduation a job is already waiting for them in their father's company, just like joining the family business, and even when they are broke, they can easily walk to the bank and borrow money from them, and they will be given easily because they have a better collateral, and even their family name speaks for them, so it's quite normal to me.

As for Bitcoin investment, you can't compare yourself with the rich guys that can buy one Bitcoin at once, while your can't achieve achieve such thing in years of accumulation, so they have more advantage than the poor.
