I think the most coolest & Bitcoin-friendly countries should be "El-Salvador" & "Central African Republic" simply because in those areas Bitcoin is fully legalized as legal tender and as such could be easily accessible by citizens without stress.
You still haven't found out that Bitcoin is no longer
"legal" in CAR? Even when it was official, what do you think it looked like in real life, most people don't even have the internet, let alone know what Bitcoin is?

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.
Considering that I am a resident of one of the listed countries, I can say that i really have no objections regarding taxes because it is possible to pay 0% tax if a certain condition is met (sale 1 or 2 years after the investment). As for other things, I can say that there are no bans on using BTC and other cryptocurrencies as a payment method, and many are adding this option to their online stores using payment processors that of course protect them from the volatility of cryptocurrencies.
