Well, the population of Russia allows it to come in second place, a large proportion of young people are engaged in the crypt.
If you are interested in the age of the miners, then this is not 16-25 years old.
Basically, I see people from 30 to 50 years old and older, and it's not getting any younger. These are businessmen who have experience in IT, engineers and people with a technical mindset. Investing in mining requires a lot of initial capital, and young people do not have such opportunities. One small container for 100 ASICs is at least 20 million rubles or $240,000. This is big money in Russia.
