> Now the Euro is heavily traded in forex markets, and surely the price fluctuates. Is this statement true?

It is not true, because currencies aren't assets. Currencies are a medium of exchange. Their job is to hold value for only as long as it takes you use them to buy necessities or invest them in assets. That's it. Any longer is a non-goal. Goals include low transaction costs, high transaction speed, fungibility, stability and predictability.

As for the FOREX market, that's a highly leveraged speculative trade on the relative purchasing power of a pair of currencies. That's not an investment and it's certainly not an asset.

With that in mind FOREX is widely regarded as a zero-sum market in the same way options and futures are. Money from the winners goes to pay off the losers.

> In this case, citizens of Zimbabwe who bought Euros very likely got back more of whatever currency they eventually converted it to than they would have if they had kept their money in Zimbabwe dollars.

This would have been a zero sum trade, not negative sum. Zero sum doesn't mean reversible or that there aren't winners and losers, just that considered as a whole, between all participants, no money left the system and no money entered - what was there was simply redistributed.

I think you're missing the point I'm making, which is that bitcoin is also (legally now, at least in El Salvador) a medium of exchange
Ok, it has the title, but its an awful medium of exchange by any objective measures. Giving it the title doesn't suddenly make it fit for purpose. To borrow a turn of phrase, if my Grandmother had wheels she would have been a bike. [1]

Bitcoin being negative sum has nothing to do with its title and everything to do with its intrinsic characteristics. I believe a study showed its PoW model extracts as much welfare from the system as a ~55% rate of inflation.

I agree about all of the above; it's not a great currency, and it's certainly more volatile than most global currencies, but it is a currency. The idea of nations recognizing bitcoin or something like it as national currency (instead of their own or another country's currency) is monumental.

Personally I'm hoping the shift comes soon for proof of stake currencies with low transaction fees.
