It certainly can and it certainly did. It surely does help in reducing poverty. Bitcoin itself doesn't have the power to reduce poverty but if one knew how to utilize bitcoin, then it could be used to reduce poverty. That's why bitcoin education overall crypto education is needed to be spread to everyone. From where I live there aren't many who knows of crypto or bitcoin. Only a few knows of it are using it. So first we have to change this.
I don't think so because poor people won't see it as an opportunity but only those who have money know it. Those people who live in the poverty line never think about investing, never think about spending for their future but what is their desire now is to feed themselves every day, that seems enough for them - they keep working throughout the day, the same thing they do the next days.
Investing in Bitcoin is not really the solution to that problem but of course, can change one's life if they will try and manage it well.
