As a result of the war, Ukraine and Russia suffered alot. Due to the support from the world countries Ukraine have made themselves strong. On the other side Russia have played a tactical game. As Russia is a big exporter of oil and gas, they were able to make ruble strong even when the European countries made sanctions. During the same time period the cryptomarket boomed as Ukraine started to receive donations in the form of cryptocurrency and Russia used it as a tool to overcome the sanctions. We've been experiencing massive food inflation as the major exporters of wheat weren't able to do business amidst the war. The 100 day war on Russia have made a big impact in the world through different means.
I do not think that Russia uses cryptocurrencies to circumvent sanctions (although, of course, I could be wrong).
According to businessman Chichvarkin, after February 24, 2022, 4,000,000 people emigrated from Russia. Educated and wealthy people emigrated (bankers, entrepreneurs, programmers, journalists).
At this time, currency restrictions on the movement of capital were introduced. Therefore, many used cryptocurrencies (in particular, bitcoin) to transfer their capital abroad.
Also, many young Russians leave Russia in winter for warmer countries (for example, Goa). In the spring, these people faced such a problem as blocking bank cards (Visa and Master). To make payments, they used financial schemes with cryptocurrencies (bitcoin and stablecoin).
All this had a positive impact on the cryptocurrency market.
Cryptocurrencies began to be used not only for speculation, but also for real financial transactions.
