This is an infographic for the distribution of 16 mining pools. If we take the facts that Bitcoin mining is banned in China, we will find that mining from unknown pools represents about 1.3% and therefore still does not constitute a large percentage of mining pools. The percentage was greater than 30% in the past.
Where is the Russian hashrate on your chart? Russia ranks 2nd in mining 
Russia has emerged as the world’s second-largest crypto mining country, overtaking Kazakhstan, according to reports from Bitriver, Russia’s largest bitcoin mining provider. While the United States remains the largest crypto miner, generating 3-4 gigawatts of mining capacity, Russia’s capacity reached one gigawatts in the first quarter of 2023. China, which banned crypto mining in 2021, did not make Bitriver’s top 10 list.
