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.
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!
Big-money guys become even bigger, and the rest are still where they are.
So, yeah, adoption-wise and overall - good, I think, for all the usual enthusiasts like us - nothing would change.
