I really do not know much about bitcoins, so if someone can add more info that would be great.<p>My question is from when you purchase bitcoin, or convert it back to your respective currency. Does that not have to go through a normal bank, which is still regulated?<p>Additionally, what is to stop shops from not accepting bitcoins? So you get paid in bitcoin, but can't convert it back to your currency, or no one accepts it as payment wouldnt that just make it worthless?
