I do not think bitcoin legalized as a legal tender should be included because bitcoin has been made a legal tender in just two countries which are El Salvador which was the first country, and Central Africa Republic (CAR) which was the second country. Go to those countries and spend bitcoin, it is accepted everywhere.
CAR rejected BTC as a legal tender a long time ago, and I don't understand why people keep repeating it as if something will change if we still believe that Bitcoin could have succeeded in a country where 90% of people do not have access to the internet. Even if you go to El Salvador, you cannot count on being able to pay with BTC anywhere, the law is one thing, but the reality is something completely different.
For other bitcoin friendly countries like Netherlands, Slovania, Switzerland and many of them. If people are from these countries, this thread can be helpful to let us know the level bitcoin is accepted in these bitcoin friendly countries. But I think tourists will spend bitcoin easily in countries that has been made as legal tender. The third for tourists is an island in Honduras where bitcoin is also a legal tender.
I assume you mean Slovenia, which is often mentioned (although I don't see any particular reason), because Portugal or Germany are also very friendly countries when it comes to Bitcoin, especially taxes. As for Honduras, it is not true that Bitcoin is legal tender there, but it is a tourist project of the Santa Lucia enclave called Bitcoin Valley. A similar thing exists on the Philippine island of Boracay, and BTC is not legal tender there either.
Your idea that Bitcoin can only prosper if it is legal tender is completely wrong, because forcing someone to use something they don't want is counterproductive in most cases.
