It seems like this might be fake news according to this article which is in Russian :
https://www.rbc.ru/economics/09/01/2019/5c36271a9a79472653e32608I don't speak Russian but from what I got with Google Translator, Russians have changed $100 Billions into Yuans, Yens and Euros. There was no plan of changing them into BTC (or is this about another $100 Billions ?)
That's what Google Translator gave me :
"The Bank of Russia has transferred $ 100 billion in yuan, yen and euros
It became known, in which assets the Bank of Russia was transferred from the US government securities last year. About $ 100 billion of gold reserves were transferred to the euro, Chinese yuan and the Japanese yen.
In April — May, Russia arranged for an unprecedented sale of US government bonds, getting rid of $ 81 billion worth of papers in two months. This happened immediately after the April round of sanctions against Russia's largest businessmen, including Oleg Deripaska and Viktor Vekselberg, their En +, Rusal and Renova companies. RBC wrote then that the Kremlin and the government are considering the toughest scenario of sanctions, including the disconnection of Russia from the interbank SWIFT system.
Information about Russia's withdrawal from US Treasury bonds came from the US Treasury Department, which publishes monthly data on foreign investment in US government debt. But in which currency Russia shifted, it was unknown.
Based on the information provided by the Bank of Russia, and the calculations of RBC for the second quarter of 2018:
The Central Bank has reduced reserves in dollars by about $ 100 billion (from $ 201 billion to $ 100 billion);
reserves in the euro increased by about $ 44 billion (from $ 102 billion to $ 147 billion);
reserves in the Chinese yuan increased from the same $ 44 billion (from $ 23 billion to $ 67 billion);
reserves in Japanese yen increased from zero to $ 20.6 billion "
