You'd need a moderate amount of faith in ETH price over the long term to make this profitable. At current prices you might make your money back in 12-18months.
Really interesting to hear this story and to leave the personal context to the end makes it even more impactful. The perseverance and creativity that this person obviously had to show to get this to work for so long are really inspiring, even if lots of other people have done similar things before. I really hope things get better for your country soon.
