Edit:
The poor don't even contemplate about investments.
Bitcoin is clearly helping some poor countries with high unemployment economies. I don't know if those people are really invested in bitcoin, but they are doing bitcoin and crypto-related work and it really gets them through the tough days.
I myself used to be unemployed and have no outside income, I came to bitcoin and must say that it has contributed to my income. Things are stabilizing now and I have also accumulated a small investment, not too big but my life has changed a lot since I got to know bitcoin and crypto.
By the way, OP, the article is just trying to shill about Electroneum rather than about the benefits bitcoin is doing in poverty alleviation as your title suggests.
