We have a catch-22 situation. 10 or 20 or 100, doesn't matter. If bitcoin is only used as a savings mechanism, then fiat wins because its still the currency and still funds tyranny. But if we have a vibrant bitcoin economy, meaning it becomes currency, then the etf's and any other traded fund that derives value from holding btc will have a supply to buy with fiat, continually removing btc from the market until none is left.
The second scenario may appear favorable because we can (supposedly) soft fork in more decimal places and then "its going up forever, laura." Or whatever her name was... But that scenario is an argumentative point to prove absurdity, like Schrödinger's cat. BTW, it's insane how many people take that cat as simultaneously alive and dead... The point was to prove absurdity. Its like in most math problems, at least the ones grounded in real world scenarios, you have to discard infinity solutions. So, this isn't that, but I think I'm justified in assuming "infinity" isn't going to happen.
What breaks? Idk, but something... It also reminds me of the credit cycle - you can see the credit cycle has topped by looking for yield inversions, assuming the yields referenced are actually the relevant numbers (might not be anymore, but theory is still good). Once you can say for sure the credit cycle is topped, meaning new businesses are getting negative returns on every dollar borrowed, then a "deflationary event" has to happen. You can't predict where it will happen, that would be another absurdity, but you can be sure it will happen. So bringing it back to bitcoin - what will happen? Something that brings a sensible equilibrium between the infinity the funds hold and the actual value traded outside the funds. It'll crash. Repeatedly. Forever. And boom repeatedly. Forever. As long as fiat exists.
The problem is, I don't see anything actually wrecking fiat. Fiat is designed to wreck. Forever... And it never dies because states exist. Its like the monster Mao, the handsomest man in China (I heard that in China) said : "power grows out of the barrel of a gun." Real power is the market, but violence controls markets. States are violence.
I *really* want bitcoin to be the one global currency. But my reasoning ability hit a wall. I think it can only be savings. That's not good enough for me. And that's all I got, cuz I don't see anything better.
