Thank you for your thorough reply.
For people looking to earn for a living here, I think that most (especially at these prices) are fooling themselves unless they live in a place where it is very, very cheap.
It's not very cheap in South Africa, but for us the rand/dollar exchange rate is good. We get R17 for one dollar and that help. It can help to supplement my income.
This is good to know. I like that I am able to give accounts like @papilloncharity some support and perhaps it makes a difference in a life or two off chain. If prices increase, my support can stay the same and increase proportionately.
