Think of it, Bitcoins do not have a tax.
maybe you need to rethink that when you cash out your giant bitcoin profits. depending on where you live you're gonna find it certainly does have tax and your ass will be nailed to the wall if they find out you haven't paid it.
I think what Pouch was referring to was the sale of items purchased by bitcoins, which is taxable of course, so he was wrong on that front as well. Take a bank debit card to the store and buy something, you get taxed. Take a BitPay card to the same store and buy the same item, you get taxed. Taxing happens at the point of purchase on THE ITEM purchased, regardless of the currency used.
Correctly said if you are buying bitcoins through fiat currency then automatically it comes to taxing as in this trade fiat currency is involved. But what ever you are earning freely that is non taxable but it differs on each country taxation system
