I like the S combination with the @ symbol. Not many people use Satoshis currently because the price is still too low they are using smaller denominations of BTC like mBTc which is 1/1000th of a bitcoin. It would be cool to get this symbol added to keyboards eventually.
Its not too low, its actually good. Things in my country are coincidentally now expressed in satoshis, because the fiat is on par with them (but soon its going to be 2 fiat for 1 satoshi) but while we are at it things work just fine:
Drink? 16 000 satoshis. Pringles? 30 000 satoshis, coffee 6 000 satoshis, 500gr of sandwich bread is 20 000 satoshis.
The "Big" stuff is expressed in millions. A 50" LCD 4k tv is 4 500 000 satoshis.
A whole bitcoin is 100 000 000 satoshis, something you might see when buying property or for the national budget i guess.
If you think people cannot live expressing prices in thousands, and millions all the time, you have always used perfect "strong" fiat coins. Me? I'd be glad if they declared the satoshi the national coin and dropped the garbage fiat we use.
I'm going to miss expressing things in satoshis real soon... stupid politicians thinking printing money solves everything, can't wait for a world without government and institutional control over currency...
Oh, i have said this before, anything beyond satoshis and bitcoins is useless, especially mBTC, there is nothing more useless and confusing than that. I particularly condemn whoever came up with
BIP 176, DO NOT WANT jaejoon.
