All we have to do is wait a big longer, when big nations do not care about crypto, they do not make good enough laws about it neither, but when smaller ones grow to be bigger thanks to crypto, bigger nations like China and the USA will have to put supportive laws as well otherwise they will be left behind. They need it to keep their power over the world and keep being world powers.
They have seen the benefits of crypto during this war. When all the establishments are being destroyed and torn down, they have no financial institutions to go to. And with the huge amount in crypto that they received during this war situation, they have seen the power of crypto in the middle of this crisis. So there's no doubt they will legalize the crypto-related businesses in their country. This will also help their people transfer their money into crypto while the situation is still vulnerable. Though, people should know the possible factors involve like volatility, which is a long running issue in crypto. But for now, making transactions during this war is easier in crypto rather than via the traditional banking system.
