Nothing has realistically changed... The United States continues to be the dominating force in the West and Russia rather than being the superpower which desires to be, it is stuck with a GBP which is lower than the ones of smaller countries in Europe.
I will continue to wait and see if ever the countries which are part of the coalition date to issue a common banknote, until then it is all hot air to me.
Nobody know the future. BRICS is simply doing what it takes to get out from under USD dominance, while making the best money they can make off the USD as it goes down.
Check out "BRICS mBridge 'Dollar Killer' Goes Live" - https://bitcointalksearch.org/topic/m.64189166. Then work on finding out what mBridge is all about, and how you can join with a little cash so you can trade with countries who are dropping the USD.
If it isn't practical for you at this time, keep on waiting.
