If you can take risks, then Bitcoin is the most profitable for You. Many of us know about Bitcoin, but we cannot take risks. Without risks, no one can succeed by investing here.
I am afraid there is really no investment that comes without risk. All investments have risks, it just depends by how much. So extremely poor people really can't afford to invest in something because the money they have is only enough for their daily survival. Even if they manage their money well, it will be almost impossible.
That’s why they are poor, and will always keep beating poverty if they don’t get out from their comfort zone and start taking risk on bitcoin. But nevertheless, I know it’s easy for us to say to invest in bitcoin, but in reality, there is actually no guaranteed profits especially that bitcoin is a highly volatile asset. It can be profitable for now, but we really can’t be sure of its future.
However, there are still few poor investors who risk their hard-earned money with bitcoin, and I believe they don’t regret taking risk with bitcoin, especially if they invested while bitcoin price is cheaper compared today’s current price.
