It is also not strange that the Nigerians are very curious about this technology, because Nigeria are perceived as the "Scam Capitol" of the world. We know Bitcoin's pseudo anonymity provide some hiding place for criminal activities, so
some of these people are actively looking for a payment method that cannot be traced.
I am not so sure that's the main reason for Nigeria being so high on the list. AFAIK, Nigeria has one of the biggest percentage of the unbanked people in the world so of course cryptocurrencies are a way for many to pay everyday stuff, hence such popularity.
I mean, using your logic that would make countries like Slovenia, Switzerland and Austria scam paradise as well and if you check the crime stats you will see that those are some of the most secure countries in the world.
This is interesting because it's all over the place. I was expecting maybe lesser developed countries to be more interested, but that also goes hand in hand with how many people have access to the internet in those countries. I can't really make much out of this besides the fact that this diversity shows us that crypto is attracting people from all spheres and classes, and that's a good thing.
This list comes from Google trends, and the way its calculated is that it measures the popularity of specific search relative to all the other searches so its not really important how many people have access to the internet. This is how it looks when it comes to top 5
Values are calculated on a scale from 0 to 100, where 100 is the location with the most popularity as a fraction of total searches in that location, a value of 50 indicates a location which is half as popular. A value of 0 indicates a location where there was not enough data for this term.
Note: A higher value means a higher proportion of all queries, not a higher absolute query count. So a tiny country where 80% of the queries are for "bananas" will get twice the score of a giant country where only 40% of the queries are for "bananas".
