El Salvador made bitcoin a legal tender, Singapore has not made bitcoin a legal tender, the second country that makes bitcoin a legal tender is Central African Republic.
There are many crypto friendly countries that do not make bitcoin a legal tender, but still accepting it as a means of payment and for investment.
Singapore categorizes Bitcoin and Altcoins into investment assets, just like my country does...
Southeast Asia has a fairly large interest in cryptocurrencies, making many countries in Southeast Asia think hard to remain friendly with cryptocurrencies.
my country in recent years, not against cryptocurrency circulating here, our government only opposes using the cryptocurrency for payment (legal tender)
in this case, the positive effect that the government can get is a tax from crypto. The growth of cryptocurrencies cannot be stopped by anyone, making them friends is the best decision that many countries have to make.
