This is like anything else, people feel that they're not going to get caught and that they're above the law. Yes, some of you may be able to make it out and not have to pay any taxes -- but you're not going to be able to show this money ever. So, if you don't pay taxes on the capital gains that you incurred with Bitcoin you're going to be screwed if you want to buy a house with the money, or a car, (and so on and so forth) While it does suck to have to pay your taxes, you're going to have to or you're going to risk an audit that could really screw you with penalties.
In my opinion, it depends on a country if they are regulating crypto. As far as i know, the government has not regulating it yet. They have no rights to to ask for any tax payment. Even in our country, the government has no power over crypto. If time would come that cryto would be centralized then people are oblige to pay taxes.
Not true, most (if not all countries) have capital gains tax that Crypto gains are going to apply too.
I would agree that there is no such thing as tax in bitcoin, if this is taxed then other users will be disturbed in terms of payment and also in the case of good and true business.
This makes no sense, just because there is no specific tax doesn't mean former taxes (such as capital gains) don't apply.
