in my country bit coin has no tax. just we have to pay for transaction fee only. in my country we have to buy more bit coins for that we did not pay tax. but we have to pay for transaction fee only. this is my country process but in some country's they have to pay for bit coin tax and transaction fee and all kind of fee. so we try to buy in wich country bit coin price is low. it is better because we have chance to skip tax.
