I like it like it is right now. If it is accepted as a currency then maybe taxes will be imposed on it and you need to declare all profits to the revenue agencies. Now it's a little bit like the Wild West but it's has its advantages.
Why do you think that governs will tax bitcoin? If its accepted as a currency for governments they couldn't tax it. Dollars, and other currencies aren't taxed. In some countries gold coins (inversion gold 0.999) aren't taxed. I don't see why governments would tax it.
