A friend at one of the local newspapers asked if I could do a piece on cryptocurrencies. I told her that I would research and maybe do a piece on the socioeconomic impacts of blockchain and cryptocurrencies on the poor. I'm looking articles/blogs/etc. to see what's already been said and what I might be able to add if anything. Any suggestions on such articles? Or maybe even academic papers that might be about the economic impacts cryptocurrencies and blockchain could have on the unbanked, migrants, folks in poverty, seniors on fixed incomes, etc. ?
