The divisible by 100 million is news to me. Unless you mean the decimal places in which case yes I know? Or did they change the code to allow for them to split some time in the future? I thought the code was already written to reverse-split the coins, down from 21 million to 10.5 million.
It’s the decimal points. I think it’s eight places (hence “bit” in Bitcoin.). That hasn’t changed since day 1. Although many people don’t understand how divisible it is.
