Would be interesting to see how pricing in sats vs whole/decimal btc terms plays out on people buying and selling.
Don't think you'll see things priced in btc (sats or otherwise) for the simple reason that you don't know what the value of something when it's denominated in btc. Nobody in the world is equipped to think in btc-denominated transactions. If I try to sell you a car for .5 btc, you really have no idea if it's a good deal or a rip off unless you know how much btc is worth in USD and do the conversions. Denominating in purely btc is impossible because bitcoin doesn't hold a stable value. You would always need to know the conversion rate to USD to evaluate the price.
