but if you live in can you dont have to pay taxes if your gambling in fiat
You have to pay income tax if you exchange BTC to fiat. Obviously you can deduct the amount of fiat exchanged to BTC, so you pay tax from fiat profit
vendetahome gave the definitive answer for this thread for now. Until CAD and other governments start taking bitcoin for the payment of debts, they'll be treated like securities--not taxable until liquidated. This is not going to happen for a long time, unless international financial markets crash big time.
