Let no one be offended, but to me it seems like a bunch of random nonsense, especially if China is in the top 10, and also Thailand, which banned cryptocurrencies as a means of payment about half a year ago, as well as Turkey, which is on 12 place. What kind of adaptation are they talking about then?
Let us take China as an example. China banned crypto and crypto mining in 2021. Bitcoin mining hashrate in China went to 0 in July 2021. But now, China bitcoin mining hashrate as gone up to significant level again as I read about it in early days of this year. China banned bitcoin and bitcoin mining, but I do not see it surprising to see China among the top countries on the list, even now the second, after US which is the first. Taking the place of Kazakhstan, which was second after the ban, now the third.
You can check Statista data about bitcoin mining hashrates here:

China returns as 2nd top Bitcoin mining hub despite the crypto banIt was news, but according to what I have found out, the news was never a lie.
Let us differentiate between implicit ban and total ban. Any ban that is related to the the arms of government not involved are just implicit ban. If the ban is not passed into law by the legislative arm of government (I am using my country as an example), that is not a total ban and the citizens still have right to buy and sell crypto individually, but not for businesses etc. Central Bank and Security Exchange Commission ban are all implicit ban, they can not stop citizens to totally stop the use of bitcoin or other crypto.
As you pointed out, our country has pretty good crypto laws and is one of the rare countries where you can go to a physical crypto exchange and buy/sell crypto without doing any KYC (up to a certain amount) + that you can also buy and sell crypto in our post offices, yet we are far behind countries that have completely opposite laws and where is much harder to do any crypto related thing. Same goes for our neighbor Slovenia that is ranked even lower while its probably ahead of us when it comes to crypto adoption and should have been much higher.
Let us take Nigeria as an example, the Central Bank of Nigeria banned (implicit ban) the use of bitcoin and other crypto in the country, but it is the first country in Africa on the list. We that lives in Nigeria knew that Nigerians are so much involved in crypto trading and other usage because Nigerian Naira is declining at a higher rate and the inflation has so much more gotten worse.
I think we should also take the methodology used into consideration.
Nominal estimation is not used. Instead, purchase power parity is used. If the cryptocurrency value received at centralized exchanges, weighted by purchasing power parity (PPP) per capita, on-chain retail value received at centralized exchanges, weighted by PPP per capita, Peer-to-peer (P2P) exchange trade volume, weighted by PPP per capita and number of internet users, on-chain cryptocurrency value received from DeFi protocols, weighted by PPP per capita and on-chain retail value received from DeFi protocols, weighted by PPP per capita are not estimated in PPP, but instead nominal, the result would be differ and likely be towards the direction you think your country should be.
