Well this is an interesting interpretation. underdeveloped Countries like Nigeria, South africa and Ghana are getting a lot of outsourcing work these days which implies they are searching for some interesting opportunities to earn BTC. Naturally in such third world countries earning even a few mBtc is enough for a week's meal so they are really into it. Also high population rates in countries like Nigeria is a reason for this interesting statistics. Surprising is to see India on number 53, it is a country with highest number of internet users and it has a hell lot of outsourced work. It must have been atleast in top 10. I think may be the restriction by the Govt. has made the searches go low.
You are clearly underestimating South Africa here, mate. Let me correct you. South Africa is not underdeveloped. Neither is it a third world country. I guess you are with the assumption that when a country is in Africa it is a poor underdeveloped country. That is wrong. It is a bit offensive to say that in that country a few mBTC is enough for a week's meal. Although there are poor people in that country as there are in India and everywhere, your generalization seems to be hasty.
The data shows how Bitcoin is gaining traction in the African continent. That is a great sign that adoption in that region is growing.
I can help you guys out. I live in South Africa. Technically it is a third world country but think of it more as mix. It is like a third world country with some first-world infrastructure. Almost everyone has a phone and thus internet access. We have fibre internet as well. Half the people here are jobless and the minimum wage is $1.35-$1.50/ hour. The largest sector is the labour sector and is also the worst paid. Salaries between $250-$400 are common. Working at a pharmacy will ean more then at a supermarket, for example, it pays 2x more. This I call semi-skilled work. Semi-skilled salaries are between $350-$600/month Skilled work pays anywhere from $600-$2500.
Most of my friends and people my age I know make between $500-$1200 there are one two that make over $2000/ month.
The living costs are.
Rent= +-$200-$800 or so on average.
Things cost bascially 2x less then people from the USA and UK pay.
You buy mcdonalds in the USA for $10 the same meal is here for $5
The cost of technology and things we import like cars and things are about 30% more then what you pay in the USA.
ADSL= $15-$30 for 10mb line and fibre is $30-$80 for 10mb-200mb line
Bread= $1.25
1 gallon milk= $3.25
1 gallon fuel is almost $4
But we love crypto here and there are many places that accept it. Online only though for now. There is ne massive market that is our version of amazon called bidorbuy.co.za and everything there you can buy with bitcoin and have it sent to your address. We also had payfast.co.za which is like bitpay but they no longer support bitcoin since the fees are not constant and the price changes too much they said they will still support crypto but only in the future so who knows what will happen there. That large market bidorbuy.co.za has most of what I need otherwise I buy elsewhere online with fiat. Delevery takes 2 days on average.
