As of my last update, there are no official websites commonly used for buying and selling bitcoin in the North Korean city of Pyongyang. The North Korean government strictly controls internet access and online transactions, making it difficult for residents to engage in cryptocurrency activities.

However, it is important to note that North Korea has been accused of using bitcoin and other cryptocurrencies to evade international sanctions and fund its illicit activities. There have been reports of North Korean hackers targeting cryptocurrency exchanges and stealing funds to support the regime's agenda.

If you are in Pyongyang and looking to buy or sell bitcoin, it is advisable to exercise caution and ensure compliance with local regulations. It is recommended to seek guidance from financial advisors or legal experts familiar with the cryptocurrency landscape in North Korea.

Overall, the use of bitcoin and other cryptocurrencies in North Korea remains a complex and sensitive issue, given the country's isolation and reputation for engaging in illicit activities. It is crucial to stay informed and vigilant when dealing with cryptocurrencies in such a high-risk environment.
