Holding and investing on bitcoin and other crypto's is not taxable per se, but if you are going to exchange it then paying tax comes into picture. Of course we have to pay taxes, as much as we want to avoid it, for now I guess we can't do anything about it. But we have to look at it at the bright side my friend, there's a lot of country that is against bitcoin, but most of us who have been in a bitcoin friendly country is enjoying the benefits. However, if the government decided to put a regulation that will include taxes, then I'm open with it. Our local exchanges have been KYC/AML complaint so I guess that I will have to pay tax sooner or later. And I would like to think that my tax will go on government projects so I guess I'm fine with the taxes.
