Can cryptocurrencies circumvent US sanctions?

Can cryptocurrencies truly bypass the stringent US sanctions that have been imposed on various individuals, entities, and even entire countries? The decentralized and borderless nature of cryptocurrencies seemingly offers a way for those targeted by sanctions to conduct financial transactions with less scrutiny. However, are there practical limitations to this? Do exchanges, wallets, and other service providers comply with sanctions regimes, effectively restricting the ability of sanctioned parties to utilize cryptocurrencies? Moreover, does the increasing regulatory scrutiny of cryptocurrencies by governments worldwide pose a challenge to this potential circumvention? Understanding these complexities is crucial for evaluating the effectiveness of cryptocurrencies as a potential tool for evading US sanctions.
