Wrong. A satoshi becomes one cent at $1 million, not $100k.
It'd be nice to have a unit of say like 1000 satoshis. One satoshi is too small an amount to use as a unit of account, whole Bitcoins will be too big for most people as the majority of people in the future will only have 0.x or 0.0x bitcoin. Having like a kilosatoshi (ks) would be nice. That way 0.1 BTC could just be called 10,000 ks instead, so the average person who buys bitcoin from here on out would have thousands or tens of thousands of ks, instead of a tiny fraction of btc or millions of sats.
A satoshi is a cent of a bit.
100 satoshis are one bit. 1 bitcoin is 1 million bits.
You can check it in bitcoin-qt. The unit is show as ubtc.
