Yes bitcoin is totally legal, only that there are no official ways to proove that if you withdraw your profits to your bank account, those funds are for bitcoin, because it happened to me.
Once i withdrew more than $3k to my bank account and i had a lot of questions from the bank and if i didnt clarify that i was going to go jail because of "money laundering"
but yes, bitcoin is totally legal, only that there are some issues about it.
many governments in the world apply status that is still confusing, many countries prohibit bitcoin users from buying and selling goods with bitcoin but the state recognizes bitcoin as an asset, there are countries that actually ban bitcoin in their countries, but what happens is that people buy bitcoin and there are still many examples of problems faced by bitcoin, but the most important is that bitcoin is a currency that does not violate the law, which violates the law, people who commit crimes by using bitcoin as a means of evil.
