I have a bitcoin cashback app that allows me to buy vouchers with sats and get cashback in sats. I also have an app that works in a similar way, but with fiat.

Both apps only allow me to withdraw once I've accumulated a certain amount. The bitcoin app offers a lower rate. For example, for the same voucher, it may offer 3%, while the fiat app may offer 7%.

I've used the bitcoin app a few times, but I've never used the fiat one. I know I may not be able to withdraw for several months and it just freaks me out, the prospect of having to hold a fiat balance for that long, because by the time I withdraw it, that 7% may buy me fewer sats than the 3% I can lock in now by getting paid in sats.

With sats I don't care if I can withdraw the same day or in 6 months, because sats are already the ultimate storage form anyway. As long as I don't get rugged, that is. But whenever someone promises to pay you, it does require trust, you can't remove that from the equation.

Similarly, with my fiat gigs sometimes I have to wait 2-3 months to get paid, which sucks (and can even be viewed as a scam), because statistically (i.e. in terms of EV) it means getting paid less than I was promised, and less by an unpredictable amount. If they paid in BTC, it wouldn't matter how long I wait, as long as they do pay in the end, because sats are sats, no decay function (let alone an unpredictable one) built into them to include in your economic calculation.
