There will probably be some incentive to turn in physical dollars as well in exchange for DC for a time being. Probably will have a deadline and then cut the useless dollar off entirely and it won't be accepted anywhere at some point. At least anywhere hooked up to the WEF machine. Oh and can't forget they'll make you get the shot too.

Prepare now. Prepare your minds, heart, soul and do what you can to make yourself more sustainable from government. Learn skills. Learn to barter. Research and learn what other people who survived other country collapses did to make it through. Or you can just take the shot and give your life away to the Digital ID because it's the easy thing to do. Most will unfortunately.
