Yes, I agree with you about the inappropriateness of the size of the block quote. I was waiting for the other editors to fix it. I do believe that what is being stated in the quote improves the article, namely that although bitcoin is not legally banned in terms of Russian law, it is in fact banned by the authorities on a de facto basis. On the other hand it is also true - as implied in the quote - that there may be many millions of USD (it is a big economy) worth of bitcoins present today in Russia on computers owned by Russians since they bought them from and paid for them in Russian Roubles on exchanges accessible to them outside Russia - and that this practice most probably would continue with and equivalent increase in the number and value of bitcoins inside Russia. If the article would have continued to state in two sourced instances only that bitcoin is illegal in Russia, it would have projected the wrong impression that there are no bitcoins in Russia and that bitcoin plays absolutely no role in the Russian economy. I do agree that the section in question deals with the legal status of bitcoin in a country. Embellishing the section with reality improves the article.
