Only an idiot would think that 1
BTC is as low as it can be divided and bought/sold.
Do folks think 1$ is the smallest unit? Or 1 oz is the smallest unit for gold? No. All can be divided down to much smaller units. They are just the base units. It's called using decimals...
You want smaller units, then just use mBTC or µBTC. For a perfect example see,
https://bitcoinity.org/markets/coinbase/USDExactly. It takes all of 5 seconds for someone to learn that any amount of Bitcoin can be bought, not just whole Bitcoins. And it takes another 5 seconds for people to learn that the smallest unit of Bitcoin is a Sat which is 100millionth of a Bitcoin.
This is why the stories of people who didn't buy it because they thought they could not afford 1 should be entirely ignored. One has to place a limit when you are tailoring something for the populace. Otherwise, why stop there. Why not make it also accessible for the medically challenged? Absurd. The number of people who can't grasp the divisibility thing in minutes is low and can be ignored.
Absolutely not. There's no benefit to changing the Bitcoin unit, and there is something better that we ought to focus on now, rather than pricing in Sats. Besides, we do something, and I think we should always look into the negative effects of it on the market, especially when it doesn't address any particular issue or problem.
There is nothing wrong with pricing things in sats, and any service can do so if they want to. You provided no reasons as to why it is wrong, just merely stated that it is. It would be interesting to see an exchange pair in sats and how it performs compared to the main BTC pair.
