I mostly use Strike for almost everything. I don’t think there’s any way to get cash from an atm though unless that’s a new feature I’m unaware of. I still have a regular bank account for cash and checks.
My mortgage, credit cards, and a few other bills are paid directly through Strike.
I basically use a credit card to pay for things and use strike to pay the credit card. I get a lot of points I use for airfare and hotels when I travel.
I get my direct deposit put in strike and use hourly DCA.
The only issue I’ve had is that one or two of my bills I have to pay I was unable to use Strike. I can’t remember why though. Other than that everything seems to be working fine.

Nothing will happen. No one’s getting arrested.

Even a broken clock is right twice a day.
