I would say Russian cryptocurrency interest is growing at about the same rate as in most other large economies. Example: as you can see from Google Trends tool, "cryptocurrency" term on Russian and German languages is at similar figures (https://trends.google.com/trends/explore?q=%D0%BA%D1%80%D0%B8%D0%BF%D1%82%D0%BE%D0%B2%D0%B0%D0%BB%D1%8E%D1%82%D1%8B,Kryptow%C3%A4hrung). German language wins a bit even though Russian speaking internet user base (most of former USSR) is much higher than German. CryptoCurrencies finally went to mass market this summer all around the world. Germany itself has an average level of dedication, but developed Asian regions - just crazy about crypto.
