The methodology used is explained in the report.
Yeah? How come?

It's a survey and you can see how accurate it is because it tells a completely different story than yours.
I do not have indept knowledge about the methodology used but I believe it is beyond the use of noncustododial wallets. Likely including exchanges and other crypto services. The methodology used, Triple A is linked to Chainanalysis.
At least now we have a methodology. I'll go over the point of Russia and China not being in that list and focus only on methodology:
Our methodologyOn-chain cryptocurrency value received,
weighted by purchasing power parity (PPP) per capitaThe goal of this metric is to rank each country by total cryptocurrency activity, but weight the rankings to favor countries where that amount is more significant based on the wealth of the average person and value of money generally within the country.
So, a bitcoin purchased in the USA is counted as one and one purchased in India as 10 because the PPP rates are also 10:1 on the median income. Nice....
On-chain retail value transferred, weighted by PPP per capita
Again, same issue! But it gets better:
Peer-to-peer (P2P) exchange trade volume, weighted by PPP per capita and number of internet users
P2P trade volume makes up a significant percentage of all cryptocurrency activity, especially in emerging markets. For this index, we rank countries by their P2P trade volume and weight it to favor countries with lower PPP per capita and fewer internet users, the goal being to highlight countries where more residents are putting a larger share of their overall wealth into P2P cryptocurrency transactions.
So one user in the US is equal to 1 while one in India to two as the average number of users in India is barely 50% of the population. Now throwing in the 1:10 ratio for the GDP PPP, how accurate is this *** in reality?
