@luisHK Sorry but it's not clear for me. If I'd live in HK then sadly I would have to pay tax on my currency trading. Suppose that I hide my income somewhere offshore. Then how would you repatriate the funds?
I'm not sure why you worry so much about repatriating your future income. With so many accounts overseas, you sure have enough to tell authorities if they ask (and if it's a problem) that you are repatriating savings.
But afaik HK actually doesn't tax individuals for their stock/futures/forex trades despite what's written in the tax code and you can also trade under an offshore company, the ird is keen on challenging the tax free offshore status of income from HK registered companies, but not so much of offshore companies. You can then repatriate the profits of your offshore companies tax free in HK although it's not clear why if you are wealthy you need to repatriate all your money where you live. If as you claim you are paying due taxes at the moment, after you move to Asia you can then invest in European real estate legally using your offshore profits rather than repatriate them to your new country of residence.
You still have a residence permit issue though, as the investor visa in HK was discontinued a few months ago. It isn't (wasn't at least) too difficult to set up a company in HK and get a work permit as the director of the company, but than you would have to,pay some tax on this company - you definetely don't need to put all your activities under this company though, and if you have a track record outside currency trading you can skip to mention it altogether.
You may want to contact a local lawyer for that matter, rather than one of the big international accounting firms.
"Furthermore how would you repatriate money from an offshore account / structure to the European country where you live (if you'd live here)?"
Again i do not know -for large amounts at least-, i've witnessed some family getting butchered following the loss of swiss bank secrecy so I guess it's not very easy. Pretty sad, the parents managed to leave their kids a bunch of money in swiss accounts and those couldn't exploit it better than letting it sleep there than give a bunch of it years later to their home country tax authorities.
But again get used to invest internationally and teach your kids to do so as well and more oportunities will be available.
