What country do you live in?
If you do not return to check for an answer to your question and answer mine then you are, of course, just another piece of shit thread spammer with a paid signature.
I live in Canada. I guess I'm not the piece of shit thread spammer with a paid signature you thought I was. I understand that since it is effectively unmonitorable apart from when you're withdrawing it to a bank, it might not be entirely necessary to report it but I'm not completely sure about it. Obviously if you're making a large sum of profit off bitcoins then if you want to start spending it on relatively large investments you would have to explain the origin of the funds. Do you have clarification on the legal perspective of bitcoins?
