I think this is an interesting question and worth to be investigated better.
So I went to Google Trends and made a query by puting as argument the word "steemit" and as a time interval the last 12 months.
The following graphics appeared.
As you can see from the graphics is popular in whole over the world. But there is a country where the word "steemit" was searched most is China. Other countries such as Venezuela and Slovenia made it to the top ten. USA instead is even lower that Canada.
In Africa there is Nigeria and South Africa where the word "steemit" was searched most.
I wonder how the block China is doing the cryptocurrencies and to the ICO will affect future results.
Let's hope next time we see those demographics the picture would not change much for what regards China and will change for better regarding USA.
