Countries like China who happens to be one of the largest community of persons but on the contrary China is against Bitcoin, Also in Africa (Nigeria) banned the use of cryptocurrency, USA and so on
Wrong,
United States doesn't ban Bitcoin, they're open for it as you can check it on Wikipedia [1]. Only the neighbor country e.g. Canada have restrict the banking ban, but you can still hold Bitcoin.
If the government of any nations like let them banned or reject the use of Bitcoin, bitcoiners still remains strong as one community, one people, one mindset, we are not going to give up on bitcoin until every nations pulling out comes back to it and bitcoin will accepted legally and globally.
It depends on the restrictions, if the country is ban Bitcoin completely and it's considered as crime if you broke it, you would go to jail if you're trapped in honeypot. Using DEX or P2P will still able to leave trace because you're using Paypal or bank account contain your personal information.
