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.
It may have been the case that Bitcoin was recognized by poor people and that these people were able to get out of poverty by investing in Bitcoin. From this perspective, Bitcoin is an opportunity for many people. But this is only true for those who heard about Bitcoin at the time and invested in it.
Of course, Bitcoin always offers opportunities for investment, but there are poor people who cannot afford to invest even if they know about Bitcoin. They don't have the option to change their situation by investing.
If you invest in Bitcoin at the right time, you can get out of poverty. Other than investing, it is not easy for Bitcoin to alleviate poverty because it is not easy for Bitcoin to reach all of humanity and it is not easy for awareness about Bitcoin to reach everyone.
