The biggest black swan on the Russia-Ukraine battlefield is that Ukraine may suddenly test a nuclear bomb. It is important to know that Ukraine was once the largest nuclear arsenal in the world and has the complete capability to produce nuclear bombs. Russia's continuous bombing of Ukrainian power plants is aimed at preventing Ukraine from developing nuclear weapons in the future. Now that Biden is about to leave office, it is highly likely that restrictions will suddenly be lifted. Once Ukraine's nuclear bomb is online, a third world war could truly become a reality. $BTC #比特币突破10万？
