Probably the rumour may start from this proposal:
What do you think about BIP 177As they want to change the base unit from sat to bitcoin. This proposal will not be acceptable. I prefer
BIPBIP172BIP 172 which will make sat to be the standard base unit officially.
The idea would have been good but 1 BTC can not be 100,000,000 bitcoin because BTC is the same as bitcoin.
