I would advise any poor folk not to invest in Bitcoin at the moment. Just be open to it when it does become the norm. The reason blacks won’t use digital currency is because, let’s face it, the poor ones, and it’s not just blacks, but poor people are hoarders and they need to have something tangible that they perceive to be of value. Bitcoin, by the nature of its inception, is nothingness. But it’s value is based on the same damn value that all fiat currency has. You still need to go to work, feed your kids, feed your neighbors, fix your car, etc. The only difference now is that you’d be using Bitcoin.
Again, if you can’t live exclusively off of Bitcoin right away, don’t put your local currency into it. Tell them Satoshi Nakamoto said “Don’t be stupid.” When the time is right, you won’t even notice.
