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.
there is no bitcoin that regulates, no one can block and this is very safe, so this is very safe money, this is only digital money, obviously there is nothing wrong with bitcoin, someone who can be wrong is someone who uses bitcoin for purposes that really breaking the law, so legally the currency is never wrong, the wrong is the currency users, many countries refuse, but they cannot apply the law against bitcoin.
