Actually you made a valid points here.Because their was not a huge transaction without SWIFT. Russia need of some source for the transaction.If they chose a bitcoin for it. It was an amazing one.Because their will huge flow in the bitcoin and ten times rise in the price from now. Atleast their will be double of the current price.So it's better to inverse huge amount of dollars in bitcoin. The big things going to happened in a short period.
They can choose bitcoin as an alternative but they can't let it all dependent on it. Do not be problematic about swift for Russia because they have already found a way to sustain and replace it. As swift was gone to them,
Russian Banks Consider Using China's UnionPay; Big Accounting Firms Exit.That's the replacement that they have so there's no problem on them anymore and it's from their ally that's just there building connection and relationship to almost every country that needs them.
