I'm reading many articles explaining that Russia shall be cut off from the SWIFT global interbank payments system, as a sanction in response to its invasion of Ukraine. That means it would be impossible to make bank transfers between Russia and most other countries.
I see this as an absolutely fantastic opportunity for BTC.
If you can"t use banks, just use BTC and be happy.
Now everyone will learn that bitcoin is a perfect currency used in any condition. Not only Russians will need it but Ukrainians are also now relying on bitcoin. Many of them are buying bitcoin to use for their international transactions because of limited e banking transactions.
