Yes I would say decrease Fiat holdings to a minimum. My flat is owned by a 86 year old. So probably I will not bring her to accept sats for renting the flat.
But I could imagine to store my value for daly spendings in crypto and pay with a visa card, wich directly converts satoshy at reasonable price.
Like I would like to increas my amound of monthly crypto usage and try to find out where I actually already could pay in crypto directly. And maby the most adapted services for this I would be happy to learn.
