Said by the guy who says that the US laws doesn't mean anything, said by the guy who calls PWC a scam. Understood buddy.

You're talking about fiction my friend. If there is a bank which opens a personal bank account for you without visiting the bank, ever, then share with the folks, they'll be happy to know about it. Until then you're lying.
Instead of lying about the laws also, you should really check at least those countries' laws you're referring to. A NRA's trading income may be taxable in certain cases, whether you like or not.
But we can easily test this Mr. Daal. Come with me to the UK, US or a country we agree in, make some money with trading (not investments!), I'll call the tax man and ask them whether you're liable to taxes as a non resident on the income sourced from the UK or US respectively. If you're willing to do this and you're not subject to taxes on your
trading income while you're present there then I'll give you a pre-agreed sum of money. Deal?
