Using what you mentioned in the beginning of inventory losing value is actually only true if the person has priced their inventory in fiat instead of bitcoin.
So, there's even a way out of that mindset.
Because bitcoin often moves between $10 000 increments, or this year, so far it's been going between 70k and 100k, so that's a $30k change. So, pricing products need to have a longer time frame than the daily or even weekly change in price.
If it costs the same amount of sats 2 weeks ago and today, it's up to a person to choose when they buy. If they already have bitcoin, the price is stable, if they price it in fiat, or need to buy bitcoin to buy the product for bitcoin, the fiat price matters.
I fully agree with your take that it's actually about profit, cause the sales they previously got for sats and kept those sats, the value of that bitcoin has now grown, so they can actually sell less that month and still be profitable π
It's all about perspective, and changing our mindsets from the fiat system, to the bitcoin system! π
