I think Putin has considered the worst risk that his country will bear if it gets prolonged sanctions.
About this war, Russia has calculated the good and the bad. Peace is above all and does not mean self-respect is something cheap to forget.
This war in my opinion is the mere existence of Putin and Russia.
But better The path of peace should be taken...
because war is not the best way...
Putin, and therefore Russia, will be defeated in the war with Ukraine. Already, Russia is suffering crushing military losses and the Kremlin simply does not know what to do in this situation, since the attack on Ukraine itself was not calculated and planned, and the decision to send troops to Ukraine was based on false data about the weakness of the Armed Forces of Ukraine and that that a significant number of Ukrainians would be happy to join Russia. Therefore, Putin's entourage planned to capture the entire territory of Ukraine in 3-5 days.
During the 53 days of hostilities in Ukraine, Russia has already lost 20,600 people killed, more than 40,000 wounded, 790 tanks, 2041 armored combat vehicles, 167 aircraft, 147 helicopters, 381 artillery systems, 130 multiple launch rocket systems, 66 air defense systems. systems, 1487 various trucks, 155 UAVs, 8 ships and boats and other weapons.
Just yesterday, Russia has lost more in Ukraine than it has lost in 8 years of war in Syria. These are 27 tanks, 39 armored vehicles and so on. A few days ago, two Ukrainian anti-ship missiles "Neptune" sank the flagship of the Russian Black Sea Fleet - the nuclear-powered missile cruiser "Moskva", which was considered invincible in Russia due to the large number of air defense systems and other weapons.
As for bitcoin, it will not save Russia from the current sanctions. After all, not only the currency is traced, but also the movement of all sanctioned goods.
