Large financial flows, including those with the use of cryptocurrencies, cannot remain unregulated by states for a long time, because this will undermine the foundations of the states themselves.
I don’t see any particular problems on the Ethereum network, which arose due to the fact that the Ethereum miner Ethermine decided not to process transactions from the Tornado Cash privacy tool, which is now under US sanctions. If a miner, for some reason that he considers quite legitimate, does not want to process certain transactions, that is his business. Others will do it. At the same time, the imposition of international sanctions on companies and individuals cannot be ignored, especially if they are caused by a global need, such as stopping Russia's aggressive war of conquest in Ukraine. Because after that, a ban on the cryptocurrency itself may follow.
