What's the most tax efficient way to withdraw Bitcoin

So my question is, as you get taxed on any profits you earn with directly held bitcoin, how are people withdrawing it? I know there are some places you can spend bitcoin directly, which would get around the issue, but most things you purchase, won't be possible to buy with bitcoin, so what's the best way to do it without wiping out a huge portion of your gains to tax?

Please don't just reply with "HODL" or "don't withdraw it" at some point in our lives we should all be withdrawing otherwise it will have been a fruitless endeavour.
