If Bitcoin is legal tender in El Salvador, does that mean they don't have to pay capital gains tax?

Was just thinking about the implications of the El Salvador Bitcoin law for their citizens.

Most countries see Bitcoin as an asset, like real estate for example. So when you dispose it (sell it for example), that triggers a capital gain event that is taxed on the amount that it gained in fiat terms.

Now, in El Salvador, since Bitcoin will be seen as currency instead of an asset like Real Estate, wouldn't this be the perfect saving instrument? No capital gains?

I think it's similar in Germany if you hold Bitcoin for more than a year. And in Australia you get 50% discount in tax if you hold for more than a year.

Bitcoin seems to be the future of savings.
