Then you don't want a currency. For something to be money it needs to (among other things) be a medium of exchange, and nobody really wants to trade away a thing today if they know it will be more valuable tomorrow.

Yeah, I want the assets I hold to increase in value, too, or at least not decrease.

Suppose you have some control over currency. You run a country. I'm that case, so you still want the currency to gain value compared to the alternatives?

Your choice is basically: holding currency is more profitable than building a house or running a business (or lending to those who do), or else less profitable. If you run a country, do you want houses and jobs and all that kind of thing, or do you want people to do better if they choose to hoard currency?

I mean as someone managing a state. If there’s a guaranteed way to make money by holding your currency, you’re not really incentivized to invest your money in semi-risky endeavors. Why would I fund a company to make me some single digit returns if I can just hold the money? If the central bank would actively enforce a deflationary currency, nobody would invest anymore.

Why do cryptobros always refuse to admit investing exists? Forex and crypto trading are always zero sum, but you don't have to choose between dollars under your mattress or bitcoin on a thumb drive, you can actually invest in productive assets.

SPY has outperformed BTC over the last 5 years, and with far less volatility.
