I do not see much positive in this news. Banks will do the trading, they will use their citizens money to do that. Everything will be controlled at bank's end. Government will get taxes out of every trade and then on the total income. Nothing positive except some liquidity flow into the market.
The good news is that Russia might have its first indigenous exchange. According to the article, all the exchanges that operate in Russia are not based or registered in the country. I am not a fan of centralization but atleast the country is opening up to crypto gradually.
I hope Russia opens up their market for cryptocurrency. That will be a real change and a positive one. If banking controls everything related to crypto for the big-pocket investors, then it's not a real change!
Making crypto friendly policies will attract more investors, create more employment and increase government revenue on tax. The market should be allowed to operate without strict government controls.
