Hopefully this will be a positive step for crypto in the future. Indeed, Bitcoin can be an alternative for a country when it is blocked. With the use of Bitcoin in this transaction, it can trigger price movements and increasingly be given a trust by all people.
With the introduction of an economic embargo on the import and export of certain groups of goods, the problem is not so much in paying for their supply or purchase from the country that has been subject to sanctions, but in the very movement of these goods in circumvention of the imposed sanctions.
So, soon Russia will face a real financial collapse worth billions of dollars, associated with a complete embargo on the export of petroleum products to Europe. The oil ceiling is already "mowing down" Russian revenues, but the worst is yet to come for Russia.
So far, Russia is able to sell any volumes of oil at a discount to India and China, but oil products, for which Europe will close its market in February, Moscow will not be able to sell to Asia. The Chinese and Indians have their own large oil refining capacities, so they do not need oil products from the Russian Federation. They can only buy crude oil, and then at a deep discount.
The only way out for Moscow is to cut production and mothball wells, some of them permanently. Thus Russia will lose billions of dollars. No cryptocurrency will save her.
