W/ respect I thought

1- bitcoin used to not exist; so current price of bitcoin x current number = fiat that did leave the banking system

2- bitcoin is still being mined so every new bitcoin mined and sold = fiat that does leave the banking system

3- fractional reserve banking means every fiat $ leaving a bank reduced bank fiat by x10 or more? Even if the bitcoin seller gets fiat for the bitcoin, the fiat may not be re deposited into the bank, fast enough, before that fractional leverage has impact ?

I am probably in error somewhere here.
