Hi!
There are some news over the internet about sold out GPUs in Russia. Just for the record, i want to explain it.
I live in average city in Russia. There are bigger cities, and there are smaller cities (Moscow and Saint-Petersburg are not included - they are inland-empires (all money are there, and salary there is much higher)). I earn 20 000 rubles/month ($350). Pretty much everyone i know are earning the same or lower.
Here is a list of vacancies for people who are searching for job in my town. http://www.czn-nmosk.ru/files/job.html You can google-translate it. As you can see pretty much everyone are earning the same or less. And this is why so many people are start mining now.
