Is this list accurate and up-to-date?

Because last time I checked, the Netherlands and Canada aren't too crypto-friendly. They still have excessive regulations...
Similarly, Luxembourg taxes cryptos enormously, ranging from 0 to over 50% depending on the conditions (0 being for donations and gifts in crypto).

I have some doubts about the quality of this list personally.

However, Malta, Slovenia, Portugal, Germany and Croatia are excellent countries for Europeans when it comes to crypto taxation. Bulgaria and Estonia also benefit from pretty low taxes. France should be avoided, as should Italy and Austria, for example.

Outside Europe, Singapore is a good country when it comes to crypto tax, Malaysia too, the Cayman Islands, (Puerto Rico has a special status too which is very interesting), and Georgia is top of the top.

As for crypto-friendly usage and culture, because I think OP is not just talking about taxes, it's still harder to come up with a list of countries, things change quickly, and most countries are on an equal footing in this respect.
