I doubt this statement, I don't believe there are people who don't need gold, don't need real estate because those are practical and necessary everyday things. I know that bitcoin is a potential investment but the reason we chose it is because we want high returns and want to get rich quickly, not because it is safer than other investments. Bitcoin is not considered a get-rich-quick investment, but you can't deny to me that bitcoin has the potential to get rich faster than gold and real estate. We want to get rich with our limited capital in bitcoin, we cannot get rich with that money in gold or real estate, and that's why we are here, IMO.
