Or at worst, you pull up the app and it tells you the dollar-value of your balance

Same as you would checking your online banking account. Again, it's all just money of account

It would be easy. But due to fluctuations the 5$ in crypto I spent is 8$ worth of crypto later I kinda got robbed on that burger. The burger shop certainly will not use crypto because they need a business plan where values are fairly stable to project ROIs.

This seems relevant:

I see here many buzz words that do not answer any of my primary issues.....

Again, that same fluctuation you're concerned with exists in paper currency. That's literally what inflation is, a devaluation of your purchasing power as the result of too much supply over demand.

**degree of fluctuation**

That's relative to USD, but what happens when crypto becomes normalized to the point where most are trading in said currency? I'm sure if I took the exchange rate of USD versus, say, the Yen or the Pound, it'd look like that chart with volatile fluctuations

Worst case scenario, if you feel insecure about it, if you're worried that its USD value will drop right before you hit "Accept," then at worst, it just encourages more frugal spending, which I can't see as a bad thing. Don't buy unless you're absolutely sure.

Remember back in the 1800s when banks used to be conservative and only lend to people they had high-confidence could repay? Ah, those were the days ...

$1 = $0.05

what is maths?

Yeah that is relative to USD over a relatively short period of time.

@GalaxyBrainer In its original conception, a "dollar" was simply a fixed amount of gold or silver. The $0.05 is relative to that amount. The idea being that our currency has been diluted through supply and demand.

ah ok

Yeah I own some Kennedy silvers.

I find it amusing that the most popular currency during the colonial period were actually Pieces of Eight.

https://en.wikipedia.org/wiki/Spanish_dollar

Piece of eight was actually pretty good. The Bohemian Thaler was the gold standard though. Well silver standard really. The weight and purity was so good that it was thought a waste of resources to reduce them to ingots.

Exactly my point regarding crypto. It's a waste to use commodities when bookkeeping will suffice.

Ultimately, the reason why currencies fluctuate has to do with the fact that value is subjective and no two people can objectively agree on what the value of something is relative to everything else. <:dapperBADGE:437819062169370624>

I'm not disagreeing on the problems with fiat currency. What I am saying is that to actually do things in the real world a currency cannot be that volatile. Say I am a bricklayer and I am going to build houses. I will buy bricks and mortar at a price in some denomination. I will expect return for future work in some denomination. If there is a large shift in the value of that currency between my purchases for the quarter and my sales I can lose out purely due to that volatility.
