The AML policy provides a barrier for Bitcoin as a decentralized cryptocurrency. Some governments have a problem with decentralized Bitcoin so that some countries ban Bitcoin. Countries that ban Bitcoin are afraid of money laundering by corruptors or criminal transactions such as buying weapons and buying illegal drugs. However, in countries that accept Bitcoin, there is no problem with decentralized Bitcoin because that is where the advantages of Bitcoin lie. People who live in countries that accept Bitcoin are very happy because they can benefit from decentralized Bitcoin, they can buy something with Bitcoin and can also benefit from trading bitcoin because the price of bitcoin is not controlled by the government but rather buyers and sellers who can control the price of Bitcoin.
