Looking at the world map on that site confirms what I expected: I'll probably like Western countries most.
Of those, I think that Canada, New Zealand, Australia, and the US seem most promising for you.
I'm surprised to see Ireland so far up that list. That's EU, so legally moving is easy, but I find the English accent there to be the most difficult there is, the housing market is crazy, and locals aren't very happy with the massive numbers of migrants already.
Canada also seems to have lost a lot of it's laid-back image, at least from what I've seen online. But I've never actually been there.
New Zealand has other complications (which are too personal to discuss here), although I love the country. As a tourist, I liked New Zealand more than Australia.
My wife keeps saying she wouldn't like the working hours in the US.
I live in the US, and it's a good place to live. You could choose whatever population density you want: from an abandoned forest in Alaska, to a European-style city.
That's actually something really nice. I prefer small villages over big cities, but with kids in school age, it shouldn't be too remote.
And you'd have access to the financial heart of the world, with a low tax rate. (And even after the Republicans are out of office, I don't expect massive tax increases.) Unfortunately, the immigration system is an utter mess. You could probably do it with an E-2 visa, but especially for a family, I'm sad to say that it's probably safer to go with a different country. Maybe you might try applying for the green card lottery just in case you happen to win.
Looking at it from this side of the Atlantic, the US has lost much of it's "country of unlimited possibilities" image, and that's even when I try to ignore the generic "Republicans bad, Democrats good" in national media here.
With such exorbitant taxes, it would be best not to disclose your cryptoassets to the regulator at all
That would make it impossible to use your money legally in the (far) future.
With such a tax, it turns out that it makes no sense (because it is unprofitable) to own a bitcoin, and for Dutch citizens (those who are unable to change their tax residency), I believe it will be more profitable to sell bitcoins before 2028.
The same tax applies to all investments and savings. The only way not to pay taxes is by not making any "profit", and in that case, inflation will still get you in the long run.
Therefore, there is no other option but to dispose of the asset (at a profit) before taxes have to be paid.
I mentioned a tax on unrealized gains, but realized gains will be equally taxed.
To the Philippines.
I'll limit my "quest" to first world countries, I wouldn't want my kids to grow up surrounded by poverty. And again: the language.
Australia/New Zealand: Snakes, spiders.
I thought the "everything is trying to kill you" is limited to Australia, not New Zealand.
Very high prices on consumer electronics. If you want to commit suicide, there are easier ways.
I didn't expect this. A quick check: a Samsung TV that costs €700 here would cost €1100+ in New Zealand. But I don't buy enough TV's per decade to worry about this.
Welcome to the ''maybe Belgium isn't that bad'' club!

That's a nice way of putting it

From what I've seen online, many Dutch people are now considering taking this step.
As you know, the bad things here are that income taxes are really high. And in good area the cost of rent or housing is skyrocketing.
I expect houses in Belgium to be cheaper (and/or bigger) than houses in the Netherlands, so this isn't on my list of concerns.
Belgium is not in the top 20. We are somewhere in the 30s I think. But for a Dutch family it is still one of the smoothest moves, 30-60 min commute possible if he is from southern part.
US/Canada/Australia/NZ look great yeah. But family with kids factor makes immigration and settling a lot heavier.
On the other hand, the way Western Europe is "developing" now, I don't see a very bright long-term future here for my kids.
I'm surprised a country can sacrifice future benefit because they are desperate of short term gains.
Politicians don't extrapolate their policies into the far future. The short term gains are "theirs", the long-term consequences are someone else's problem.
Sadly they might push the Exit tax to box 3 before this outrageous tax is implemented
That's not possible: in box 3, you pay your taxes annually. There are no untaxed gains to be taxed later.
Have a friend that resides in Portugal and the standard there isn't bad
I've seen Portugal mentioned as a good place to live of Bitcoin many times, but again: the language

I am pretty sure there are clever ways of "legally" evading taxes even in the Netherlands but these ways probably involve setting up a corporate with a meaningful business income.
I've looked into the "box 2" route, and that solves the problem of paying tax on unrealized gains, but the tax is still quite high and it adds more admin to deal with. I don't think the added complications are worth it: government can change the rates at any time again, and might even add an exit tax to "box 2" in the future to avoid capital from moving out.
There are a few countries where personal income don't get taxed at all but then almost all of them fucked their citizens/tax residents over at least once in the past and that's why they offer these nice deals. By buying that zero personal income tax package you are also buying a huge risk. The risk is, they can fuck you over, again, when they feel like it.
That's why I'm not looking for a country without any taxes. I'm trying to find a reasonable place where we don't get drained by taxes, while still good enough to raise a family.
In other words, tax revenue for the wealth tax is going to go down. We’ve already discussed this in a thread in the Legal section.
Thanks, I hadn't seen that thread yet. I created
a long post in it.
Moving from the Netherlands to Belgium is like moving from one city to the nearest one in a larger country. Plus, you are part of the Benelux
The physical moving may be like just moving to another city, but the paperwork involved is just as real as moving to any other country. I don't think "Benelux" has any meaning left.
I live in the EU and in one of those top 5 'human freedom index' countries theymos lists
That narrows it down to 3 possibilities

and I have bever paid TAX on my Bitcoin or crypto dealings.
In a legal way? If so, do tell!
it was my understanding that Portugal was the most 'crypto' friendly EU country to reside.
That doesn't work with the language.
