If we can also get to the point of "atomic asset exchange" where different cryptos can be exchanged with each other without the use of a third party, (bitcoin for litecoin without having to use Coinbase), the cost savings for the consumer would be huge.
The question remains if Russia's crypto would be set a maximum number of "coins" to be created over a specific period of time, eliminating the inflationary effects of trying to manipulate the economy by excessive creation of more.
My guess is they would use the crypto for the time and cost savings, but not for the economy advantages that come with decentralized control.
