Anyone who is interested in Bitcoin should understand more about the legalities surrounding the world's first decentralized currency. A part of this is knowing where bitcoin is legal.
In reality, Bitcoin is legal everywhere from the perspective of the Bitcoin blockchain. It is open to all people around the world. At a national level, it may be prohibited to use.
In most nations, Bitcoin is regulated but legal to own and use. Some nations, like China, have banned Bitcoin outright, but this is a nuanced situation.
China remains one of the largest Bitcoin mining nations there is, and many exchange operators began in China. Despite this, the Chinese government maintains that it is illegal to own or use Bitcoin.
Some nations, like Singapore or Panama, have made it very easy to use Bitcoin, or develop crypto or blockchain-based businesses.
With clear regulations and advanced financial services, both nations are examples of how to make cryptocurrencies legal and regulated. If you need to know more about the legality of Bitcoin in your country, the biggest issue is likely taxation.
Be sure to start with an accountant that understands crypto taxes in your country, so you can stay on the right side of the law. There are very few countries where Bitcoin is totally illegal, so don't worry, and do a little research about your local laws.
