I'm not quite sure what you mean by "Does anyone else collect NBA moments?" is it a game? or whatever @crazy-andy mean! But I like this image. Simplicity in making money, with all limitations [a few piles of tomatoes, cayenne pepper, ginger and onions] the girl tries to sell something for money. How do you think of the country of Ethiopia when you visited it Mr.?
Yes, NBA Top Shot is something like a game, but also an investment or collection based event. It become very popular. So far you can also earn a lot from it, but only with investment.
On the photo which you exposed we can see totally oposite thing. How the market actually worked in the past as well. Now some of us are buying something online, which is actually "in the air", but in some places of the World you can only see traditional marketplace.
I was in Ethiopia just before COVID craziness, so in January 2020.
