Best post I read on here today.
I don't have any numbers, but what are the annual maintenance costs of the current fiat system in comparison? Probably not 9% like with bitcoin today, but definitely not zero either (banks, vaults, security systems, ATMs, personnel, printing bank notes, minting coins, credit card fraud, insurances etc.)? Sum it up and you will know how many more halvings until break even. Just a thought.
