I wouldn't step outside my house without a credit card with 10K in case something went wrong. I brought four airline tickets this month and my statement was 960.34 this month (just paid it)You gotta have at least $500-1000 ready to use in case of emergency if you're traveling. Not counted with your expenses, it has to be separate and ready to go in case of some fukkery happening at the airport, hotel, whatever.
When I first went to the DR I had pneumonia I thought I had COVID was rushed to the hospital and they wheeled me into the cashier windown and swiped my card. I was told that that would usually admit me but the hospital was full of COVID patients walked out with a charge for 1425.00
