Please apologize: you made a clear mistake. 

You are making a big mistake on Bitcoin: You removed my reliable source. THis is what you removed - including the reliable source - reliable as per Ladislav Mecir a very accomplised editor: 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 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 an equivalent increase in the number and value of bitcoins inside Russia.
Please revert your false allegations against me including that I am attacking other editors: I have a reliable source: you simply state: "Please do not add or change content without citing a reliable source. Please review the guidelines at Wikipedia:Citing sources and take this opportunity to add references to the article."

I had a source: it is in the Bitcoin article history for all to see. Please apologise and revert your false allegations immediatly.
