Depends on the country and the tax regulations there.
If you are not an extremely active trader (read: it is actually your job), you are only subject to capital gains tax in The Netherlands, which is between 0,8 and 1,8% next year.
You lucky personage. It's 18-28% in the UK and probably going higher. I will soon be imprisoned here as well so won't be able to spend that tax avoiding year making Lederhosen in Bavaria that I was planning on.
