Not sure how I should react, but with this news we can expect some blockchain analysis to mark or blacklist addresses associated with Russia. So, if Russia accept Bitcoin in order to use it for foreign trade, I don't think it's gonna work fine since it can be traced.
There are ways to remove traces (i.e. paying exorbitant fees to a certain miner),
especially if you own big mining facilities.
The next question is, if Russia want to trade with their allies e.g. Brazil, China, India, South Africa etc, why they didn't choose to use BRICS currency instead?
Spoiler alert:
There was never and there will never be a BRICs basket currency. It's vaporware.
They intended to use BTC from the get-go, they just don't want to announce it formally (yet).
Why? Because the price could easily skyrocket to 7 digit figures in a single day.
Maybe they'll announce it in 2025, but at the latest I expect it to happen by 2030.
But, the good thing is there are two big countries are trying to use Bitcoin, if China join this party, it will be really big news.
It will be really big news when
China invades Taiwan in 2027.
However, I do acknowledge that it conflicts with their plan on promoting BRICS.
It doesn't. That was the plan from the get-go.
That's why they started mining BTC a while back.
